So the question is, what is it different between a pure Khalil inbound? Ah, coat a polar couvillon down and a Iot, Nick. So first, um, Uncle Leland down is between two no medals, for example, carbon and carbon, that is a Covalin bound. And the pure Quillen bone is between two exact same Adams, for example carbon, carbon, carbon, carbon, oxygen, oxygen and hodges in hiding. Those are all pure ical in it. Bounce in the second one opponent calling them bound. A poll local inbound is between two different no medals. For example, carbon, oxygen, carbon, hydrogen. Okay. And three is ionic bound. That is, between a medal and a lone battle. So, for example, sodium chloride sodium Corrine, as our table salt and in owning bound sodium gives its electron this electron two all right. So sodium has a positive one charge, and Cora has naked one charge and a co within bounds. The electron is shared between the two atoms. For example, hydrogen has one. Adam has one electron. So, to Hodgins has two electrons shared between this hydrogen

three common types of compounds or bonds that air found in these compounds that show the spectrum of sharing and transferring of electrons are covalin bonds, polar Covalin bonds and Ionic bonds. In the case of a non polar Covalin compound or a non polar Co. Violent bond, we have no difference in electro negativity between the two elements that comprise the bond. There&#x27;s only occurs when the elements are exactly the same, such as an a c l C l bond, because there&#x27;s no difference in electoral negativity than the electrons are shared equally. And there are no charges associated with the elements comprising this bond. In the case of a polar Covalin bond, we have two elements that come together that want to form a co violent bond, which would be to non metals. However, there is a difference in electro negativity. One being slightly Mawr electron negative will result in an unequal sharing or the one that&#x27;s slightly more electro negative polls. Mawr of the electron density towards it, and it doesn&#x27;t take on a full negative charge. But a partial negative negative charge represented by this lower case Greek delta minus this means partial negative. This means partial positive as the oxygen has pulled some of the electron density away from carbon. The last one is an Ionic compound. There&#x27;s a large difference in electro negativity between the two elements that comprise the bond, typically being a metal combined with a nonmetal. Because of this large difference in electron negativity, we assumed the electrons air completely transferred. If they&#x27;re transferred, we have full, positive and full negative charges, the positive charge being associated with the metal and the negative charge with the nonmetal.

Okay, So when we talk about chemical bonds, there are really two main types Ionic Bonds and Co. Vaillant Bonds. Now, both of these are chemical bonds. So they both are attractive forces that that help hold compounds together. But they&#x27;re really quite different in a lot of ways. Caine s O If we take a look at Ionic bonds, um, one of the ways you can always spot these is that they tend formed between medals. Okay, which tend to be on the left side of the periodic table and non metals. Okay, which tend to be on the right side of the periodic table. So medals are things like with the M magnesium transition metals, which are in the middle of the periodic tables of things like maybe iron. Okay, our non metals around the right side of the periodic table. And these air things like oxygen, sulfur, nitrogen, chlorine. Okay, now, if we contrast this with CO Vaillant bonds, Cho vaillant bonds tend to form between two non metals. Okay, so they usually are going to be between elements that are only on the right side of the periodic table. Okay, Another key difference between these types of bonds is based on how the electrons in the bond behaved. Okay, so in Ionic bonds, those air usually characterized by a transfer of electrons from one element to the other. Okay, this is because the Electra negativity of medals and non metals is usually pretty different. Case A non metals are very electron negatively, which means that they like to attract electrons. Medals are usually not very Electra negative. Which means that they like to give up electrons. Eso, usually in the case of a ionic bond, we have an electron going from the metal, okay. And it can be more than one electron, in fact, to the non metal. And what happens when we transfer electrons is we formed charged species called ions. Okay, Um, a positively charged ion is called a cat eye on. OK, one way that you can remember that cat ions are positive is that you have a tea and kat I n and T kind of looks like a plus charge. Okay, um, and you have an ions which are negative. Okay, So an ionic bonding, we generally form a cat eye on on whatever our mettle is okay, because that&#x27;s what&#x27;s giving up electrons. And we usually forman an ion on whatever the nonmetal is because that&#x27;s what&#x27;s attracting the electrons in the bonding tends to be between ions. Okay, between charge species on DH. Because these charge species were just sort of big balls of charge, there really isn&#x27;t any directionality to the bonding. Okay, so when ions bond with each other, they just sort of sort of like to, ah, basketballs. And they just sort of touched and it doesn&#x27;t really matter where they&#x27;re touching. You can kind of roll the balls around each other, but as long as they&#x27;re in contact, there&#x27;s still a bond there. Okay. Co Vaillant bonds are actually quite a bit different because they usually involve a sharing no of the electrons and came Now the reason for this is that because the bond is forming between two non metals, the electro negativity difference really is not that big. Okay, all of the non metals, they&#x27;re goingto have electra negativity. Is that air pretty close to each other s O Subsequently? What happens is instead of electrons going completely from one species to the other, the electron that just sort of shared equally between the elements, okay. And what this does is it sort of creates these discreet chemical bonds that actually stay, um, in a well defined area. Okay, so ionic bonds tend to be very loose, right? You could just sort of think of two balls of charges. This kind of sticking together. Where is with CO? Vaillant Bonds. There&#x27;s actually a well defined bond between all of the elements that make up the chemical compound. Okay, So to wrap up Ionic bonds again tend to be between medals and non metals, where his co Vaillant bonds are going to be between just two non medals. All right, um, Ionic bonds. They&#x27;re going to involve a transfer of electrons from the metal which forms a positively charged cat eye onto the nonmetal, which forms a negatively charged an ion. And those just kind of stick together like, sort of two balls in charge. Now, in co Vaillant Bonds, we don&#x27;t transfer electrons. We share them equally. Okay. That creates well defined chemical bonds that sort of keep the elements well connected

Catherine Lemar · Answer

her co Vaillant bond is a bond where electrons are shared between two co violently bonded atoms and one Adam is highly Electra negative, like oxygen. And so oxygen draws the electrons towards itself, making it more negative and leaving hydrogen more positive when I on a compound is a compound between a metal like sodium and a non metal like chlorine, where sodium or the metal in general transfers the electron to the non metal. So there is no sharing of electrons in on Ionic compound.

for pure Covalin versus a polar Covalin versus Ionic bonds. So, first of all, let&#x27;s define in General Cho violent in the Janek bones. When we have a covalin bones, we have nonmetal nor mental, and they share electrons when we have another unit. Bones. We have a metal last, though, and it is completely transfer from the metal Tow. The non metal about the Covalin Bond way can distinguish if we have to atoms that are equally sharing the electrons. Then we have a pure colville in bold. And these happen when the two others of the same electro negativity, when the two atoms forming the bond of very different Electra negativity ease the electrons that they&#x27;re sharing their know, equally shared. But they will be there will be more concentrated, one of the two others, unless on the other one. So in this case, we have a caller Covalin Bond, because we have basically a disciple, so we will have a partial positive charge on one of the album in the less Electra Negative and a partial negative charge on the other, out on the one with higher little negativity. So let&#x27;s see one example for each category or to molecular oxygen is a pure equivalent is constituted by two same others. So of course they do at the same Electra negativity. And, uh, so in this case, we don&#x27;t have any polarization. And we have a pure covalin bond HCL instead. We know from the periodic table that hydrogen is a very low Electra negativity, while chlorine us Hi, Elektra. Negativity. So different electrical activity, sharing of electrons. We have a partial positive charge in the estrogen and the partial negative charge on the chlorine and the diaper moment that goes like from hydrogen toe clawed him. Ah, yearning, longing. For example, an A. C L and A is a metal C l is unknown metal. So we have a unit bones and an electron. The Valence electron off the sodium is completely transferred to the clothing. Then become now my house

Catherine Lemar · Answer

large electro negativity difference. So in water, for example, oxygen has a strong electro negativity, and it draws electrons towards itself, giving it a partial pause. Partial negative charge, leaving hydrogen partially negative. I&#x27;m sorry. Partially positive. A non polar Covalin bond is one where electrons are shared evenly amongst the elements and the molecule, and so there is no distinct positive or negative end so polar and non polar.
