Question

Why does carbon, C, have a larger atomic mass than boron, $\mathrm{B}$ , even though they each have six neutrons?

David Collins · Accepted Answer

Carbon has a greater atomic mass with six neutrons than boron with six neutrons, simply because carbon has one more protons in its nucleus than boron does.

So when you write out um the name of a substance for instance like carbon 12 That 12 is what we call the mass number and it is the mass of that particular isotope. So for carbon 12 the mass of one atom of carbon 12 Is going to be 12. And the um unit is the atomic mass unit or A. M. U. So the mass of carbon of a carbon atom, carbon 12 12 AM you. But if you were to look on the periodic table, the mass of carbon is listed as 12.011. And why is that? Well carbon can have for instance uh several isotopes. Carbon 12 is just one of those. And so for instance carbon 12 is the one that&#x27;s found in the graphite in your pencil. But there&#x27;s another isotope of carbon carbon 14 Which is used to date the age of fossils and mummies and things like that. And so now that we have different isotopes and this one has a mass of 12. I am you And the other one has a mass of 14 a. m. U. Well we can see that the masses of each of the isotopes is different. And what you might want to do is just average them together and say the mass should be 13. Well that doesn&#x27;t equal 12.11 either. It&#x27;s because when we look at the isotopes we take a weighted average. So a weighted average is like the average for your grades. Your homework is not worth the same as a quiz and your quiz is not worth the same as your exam. The exam is going to be worth more, And so it turns out in the universe there&#x27;s more carbon 12 than carbon 14. So when we wait, Carbon 12 more, because there&#x27;s more of it, the answer gets closer and closer and closer to 12. So since there&#x27;s much more carbon 12 in the universe and there is much less carbon 14, the answer is much closer to 12 than it is to 14, which is why the average atomic mass for carbon, the weighted average is 12 point oh 11 a.m. You

Okay, So for this question, the asking why there isn&#x27;t a boron with the mass of 10.81 a and you even though on the purity table they say the mass of boron is 10.81 a. M you well, one thing that we have to know about the mass on the puree table is that the mass that led label on the periodic table. So let&#x27;s just drug war on here. We have four on right, and we have 10.81 We have the atomic member on the tops of the mass year. What they&#x27;re referring to is the average mass of boron, right? This means that what is the average mass of boron in nature that can be found? So maybe boron ways, Maybe in nature, we can find a blond that has a mass of 11 a.m. U. And then maybe we have four on with the massive 10 a.m. U. And if there are more brawn that weighs 11 a.m. you compared to the amount of waste 10 a.m. you or we average the mouth and obviously we will get a bigger number 10.81 So this this is pretty much just the average mass. It&#x27;s not

Sara Vukojevic · Answer

this question tells us that carbon has six protons and six neutrons. Before we do anything else, let&#x27;s make sure we understand what that means. Protons are the positive particle in an Adam, and neutrons are the A charge lists particle in an Adam. They are not positive or negative. You have protons and neutrons in the nucleus, and then you have electrons in an electron cloud around the nucleus. And that&#x27;s what Adam is. So now that we know what this means, it&#x27;s going to the questions. Atomic number is based on how many protons in Adam has. So in this case, carbons. Atomic number is six. Atomic weight is protons plus neutrons. So that is six plus six in this case, based on our given information. So the atomic weight of carbon is 12. Let&#x27;s move on to electrons. Electrons. If you remember, they are the negative charge that is in the electron cloud on the electoral rings around the nucleus of the atom. So electrons, uh Adams at their basic state are neutral. Yes, Carbon has six positive charges, so that&#x27;s six protons needs. It needs six negative charges to make it nuclear right. Six minus 6 to 0. So that&#x27;s electrons. So it has six electrons. Oh, rights moving on two full shell. So this is talking about a Palin show, uh, for the baylin show. That&#x27;s the electron shells out here. They could be full right Full is when they are the most stable. So you have the nucleus, your first ring in order for it to be full, it needs to electrons, and then it&#x27;s happy it&#x27;s stable, and then your second ring. In order to be full, it needs eight electrons, and then it&#x27;s happening stable. So in our case we have six electrons, so we fill up the first ring, right, so first ring is full. Then in the second ring, we only have four left. So four electrons because six minus my six minus choose for so toe Philip that second ring, we have eight minus four, so that&#x27;s four electrons needed for a full Vaillant show. So what that means is that carbon is going to want Teoh, get four electrons or give for electrons away in order to have a full show. Either first show our second show and be very stable. So when we&#x27;re talking about chemical behavior, under do this and red just so that you can tell the difference. Um, when we&#x27;re talking about chemical behavior, Kurban is going to want to share four electrons by far by forming for Kobe lint bonds so that it has a full Baylin show. And that&#x27;s super important that it conform. Four co Vaillant bonds super helpful for life once for who really wants bonds, that&#x27;s what its chemical behavior is going to do. All right. Radioactive structure. So we&#x27;re talking about carbon 14 in this case, Bourbon. 14. Eso Carbon 14 has two additional neutrons in its nucleus to additional neutrons because that 14 what that means is that&#x27;s its atomic weight. So if you remember, our atomic weight is protons plus neutrons, so 14 minus or original atomic weight, which is 12. That&#x27;s two additional either protons or neutrons, and it&#x27;s going to be neutrons always for these radioactive elements, because if it was protons, it would be a different element. Because remember, your atomic number is based off of how many persons you have, so you have two additional neutrons, and what that means is that Ah, the wait is going to be more. But when it comes to the actual chemical behavior. Um, what we&#x27;re talking about when we say chemical behavior, we&#x27;re talking about forming bonds and stuff like that. And so that won&#x27;t change because that has to do with electrons and not johns. So that&#x27;s not going to change with radioactive, uh, elements. Radioactive elements have to do with radioactive decay and stuff like that, but not with chemical behavior. Radioactive have Mikel Carbon 14 is still going to want to make four co Vaillant bonds, just like carbon 12. What?

Sydney Atkins · Answer

carbon conform more compounds than any other element because carbon atoms can link up with other carbon atoms in either a straight chain. What you look something like this branched chains. She would look something like this, and it can also be in cyclical change like this, like benzene. So because carbon atoms can link up with other carbon atoms, they conform more compounds than any other elements. Also, carbon itself can make four bonds, and those four bonds can either be in single bonds. It can make double barn when it can even make triple bonds during a lot of variability with carbon atoms.

Hey, guys. So in this question were asked to explain why carbon is able to form so many compounds than any other element on the periodic table. So basically, just asking why is carbon so special? So this is due to a number of reasons. So first off, let&#x27;s look at carbons lewis dot structure. So when we draw the lewis dot structure for a single carbon Adam, we know it has four valence electrons, and we can depict that as for dot surrounding this carbon atom and this ah carbon structure, this lewis dot structure for carbon. It allows for a number off elements to be blinded to it so it can hold or has four ca Vaillant Barnes. So in organ chemistry, we usually have, um, five or six different Adams bonded to carbon. And I you&#x27;d like to use this acronym called John Thompson. So C, H. O and PS and all of this This is an acronym for the different elements that are usually in a non organic compound. So carbon, hydrogen, oxygen, nitrogen, phosphorus and silver. So these are usually the organic Adams in a ah hydrocarbon. So in ah, the carbon structure, it can usually have for Covalin Bond, or it can have for Covalin bonds, and it&#x27;s usually some either of these Adams. And because of this, we can also have the ability. Uh, carbon has the ability to form branches and chains of itself, so this could be, Ah, a chain is usually a line a straight line of carbon atoms. So let&#x27;s say we have butane here, which is 1234 carbon atoms and chain. We can also have branches or cyclic compounds. So, like cycle heck sane, which is six carbon atoms in a cyclic chain like this and branches. If we have our same butane molecule, we can have like a branch often Ethel right here, or a metal branch right here indicating ah to two carbon branch and a one carbon branch. Um carbon can also form single and double bonds and triple bonds. And because of this ability to form all of these types of bonds, this allows for even more molecules to be formed. Then just, um ah, molecules that are only single bonds. Ah, carbon is also small enough to ah comfortably have large structures like ah thes straight change or these cyclic um, structures. So carbon is just the right size. If we look at the periodic table, we can see that silicone also has four valence electrons like carbon, but it is too large to be able to have these different arrangements. So this, uh, carbon, because of its ability to form all of these different molecules that can also ah, form different bonding arrangements, which are called ice Merce. And we know that I Summers can either take structural form. So the carbon atoms and the other atoms bonded to these chains can be arranged differently but had the same molecular formula. Or they can have different arrangements in space to form stereo ice MERS. So because of all these different factors, carbon can form a myriad of different molecules and compounds, unlike some of the Adams and elements on the periodic table.
