to know which of the isotopes that are listed would be found in nature. We need to determine whether or not they are stable isotopes, as represented by the figure on page 66. If there is not a box that corresponds to a stable isotope for the element based upon its number of neutrons and protons, then we will assume if it&#x27;s not in the figure, there&#x27;s not a boxing, that location in the figure than it is not a stable isotope and is not found in nature. So we&#x27;re here. We&#x27;ve got your opium 63 with a mass number of 1 62 So that corresponds to 99 neutrons. So we go to the graph 99 neutrons, 66 protons, and we do not see stable isotope this location. So this would not be stable or found in nature for the next one. We go to arsenic uh, 75 having 75 minus 33 42 neutrons. So we go to the table 42 neutrons, 33 protons. We do see that this is a stable isotope that would be found in nature. Next one is burying 1 12 so 1 12 minus 56 gives us 56 neutrons. There is no stable isotope with 56 neutrons and 56 protons in the table. The next one, then, is some unknown element. Uh, 88 88 is going to be radium, and there is no radium isotope with 172 neutrons. That is stable. This is way outside of the zone of stability. We have far too many neutrons for it to be stable.

recall that isotopes of elements are least likely to occur in nature if they are radioactive. Also, remember that all Adams, except for hydrogen hydrogen, the isotope with one proton and zero neutrons have neutrons except for this species h one. So if we look at all of our choices, we have carbon 12 carbon 13 and carbon 14 all of which, when combined, would give us a atomic mass very similar to what is found on the periodic table of 12. But Carbon six shows just an Adam that has set the six protons and zero neutrons. Remembering that this number appear is protons plus neutrons and carbon has six protons, so it must have zero neutrons. So because it has zero neutrons, this statement here suggests that it is not possible to exist in nature. The answer, then being a

you know, for a nice element to be found in nature, it needs to either be staple and not radioactive. Or if it is radioactive, it needs to have a really long half life so that it could still be around after the formation of our solar system. After the formation of our earth, I need him 24 stable so it would be around Rome in 81 is stable. It would be around Udine, and 1 52 has a really short half life, so it wouldn&#x27;t be around. Platinum 1 95 is stable, so it would be around. Uranium to 38 is radioactive, but it has 1/2 life of 4.5 billion years until it&#x27;s still going to be found on Earth.

for discussion. Religion Yet what I so tops we could identify a settles from this few unknown elements and I saw tops. Basically, I define s atoms. We on new kites with the same amount off protons, birds different amount off neutrons A different shunts. So what you wanted to use to get the neutron Are these already proton number when the proton number is actually numbered s pillow? Right? Often labor guys say and we want to find those with these same number of proton numbers, but different number off nuclear number, right? Set The nuclear number is equals to deport a number plus the number off nutrients and f d in If two different elements have to seem proton number but different mutual number I mean different. You clone number, they won&#x27;t be in debt. They are neutron number is different, right? So to look for this for simple, we have to you first pay over here. We&#x27;ve different with the same proton number off 71 but and they also have different number off nuclear number, which is good and it they must be isotopes. Right? So this is so first pair. What&#x27;s again? Pay reef. The same Crotona, Both Senate. Four different new clone number 175 20. So this is our second pay

So here we are trying to figure out which would be following our isotopes of elements fits. So for this problem, we know that our atomic number is 9 11 x and we can go over here and look at the notation for how to solve the topic rotation. So the symbol accents for the symbol of the elements. Any stands for the last number and three stance will be atomic. So since our atomic number is lying, we onesie to halve the number nine, indicating that the atomic number is that so the atomic member basically signifies the identity of the element, while the last number just indicates how much mass it has from the amount of protons and nutrients. So each of these ah isotopes anyone that has the number nine that is indicated on the bottom of the atomic notation. There&#x27;s an isotope of of this element, so this would be an isotope of this and this would also be nice. It&#x27;ll this would not be an isotope because it has an atomic number of 18. So, um, it is not the same element

So this is a multipart question. In the first thing 1st 48 wants us to list. I know where gas elements and of these Agassi a dash to which only has which number gases have only radioactive isotopes. You can tell right away if I chose by looking to Prince sees a white owned the your table. So they put currencies around the mass. But our noble gases are huge are on and the young something she got reversed able to krypton, you know, Right? Lt&#x27;s only has a radioactive element. Well, isotope, is this one of Omega&#x27;s Shootout things That&#x27;s radioactive makes me Oh, if you&#x27;re at a table like I say, the whole numbers enclosed in Prince ease. And that&#x27;s the mass number of really the longest living isotope because I&#x27;m actually he&#x27;s regulated elements. A meat electrons until they become more stable. Now heartbeat, which about that element and we strains. This element only has one radioactive isis. We only have a direct flight systems. So the first part of the deal and then for the transition element to meet you
