Complete each of the following nuclear equations and describe the type of radiation: a. ${ }_{13}^{28} \mathrm{Al} \longrightarrow ?+-\mathrm{i} e$ b. ${ }_{73}^{180 \mathrm{~m}} \mathrm{Ta} \longrightarrow{ }_{73}^{180} \mathrm{Ta}+?$ c. ${ }_{29}^{66} \mathrm{Cu} \longrightarrow{ }_{30}^{66} \mathrm{Zn}+?$ d. $? \longrightarrow{ }_{90}^{234} \mathrm{Th}+{ }_{2}^{4} \mathrm{He}$ e. ${ }_{80}^{188} \mathrm{Hg} \longrightarrow ?++i e$

Unstable radioisotopes can undergo nuclear reactions in order to form more stable daughter nucleus. In this case, they will emit various kinds off radiation, such as have a particles beat a party, girls, positrons and gamma radiation. Let's look at some examples and try to complete the two sides off the nuclear reaction. Let's say behind a case that aluminum 28 with the atomic number 13 you have nice to, uh, B Deep article. What is the daughter nucleus that was synthesized in this process? Since the the the particle has a mass off zero, the atomic mass on the mass number off the daughter nucleus has to be equal to 28 and, uh, at the MK number. After daughter nucleus has to be equal to 14 for 14 minus one will be equal to 13 on the site. So the atomic number 14. If you look at a periodic table, you know this corresponds to silicon. So this in star beta decay off Aluminum 28. Let's look at a few more examples if we had turn to them 180 in its meta stable state, which is represented by that little M. But it's at the MK number 73 Conrad and do a tantalum nucleus that is more stable since there has been no change in the mass number. Oh, the academic number. This has to produce. Ah, 00 Get my particle. Let's look at a couple of more jumpers. Let's say they had copper 66 with the atomic number. 29. If this gave rise to sink 66 that the at the MC number 30 but did produce in this nuclear reaction. Since the mass number does not change from copper to zinc, the mask off the radiation emitted has to be zero. And to make up with the difference, Rhonda at the make numbers, they have to have a positive. I'm sorry, negative one charge with the radiation. So this corresponds to a B tobacco. So Cooper, 66 undergoes be Daddy K to farm Zinc 66. That's trying to find an example. Let's say that is a new kiss that will form, but gardening clears with the mass number 2 34 and atomic number 90. And that is a story, um, along it on Subotica. But it's going to be the bed and nucleus that under event, this nuclear reaction. Something of the mass numbers. We realize that the parent nucleus has to have a mass number he called to 38 and, uh, atomic number equaled. 0 92 And this corresponds to uranium.

Almost a nuclearized dogs can undergo nuclear reactions in order to convert into stable dartanyon p I. In this process, particles such as of a particles beat a particles. Positrons are gamma radiation will be emitted. Let's look at some examples. Let's say we started bit see Element, which has a atomic mass six. If this Emmett did, uh, if this gave rise to ah boron at them with the mass number off live on and their atomic number five, what kind of radiation will it emit in the process? So in order to figure this out, we have to balance the mass numbers under estimate numbers on the two sides of the equation. Since the mass young boys, a lot of these islands, the particle emitted here has to have a mass numbers evil. Since the atomic number is not balanced in order for both sides to have a natale MC number daughter off six, this particle has to have a charge off run. So this has to be, uh, plus it drawn that was emitted in this case. So positrons are indicated or symbolized by E and has a mass off zero. The only difference from electron is that it has a positive one charge. Let's look at more examples. Let's say we had sorry for 35 with their atomic number 16. If this Emmy did an electron or beat a particle march village form but is the daughter nucleus, it will form in the process. So it has to have a mass number 35 because yet zero. And the atomic number has to be 17 for both sides. To have a total atomic number off 16 to this corresponds to clothing. Let's just get a couple of more examples. Not say they had a nuclear phone. A dream 90. Do you carry? Yeah, We dedicate what has to be the period on nuclear, in this case again, by balancing the master over on the two sides, it has to have a mass number off 90 I the night to make number off 38. This corresponds to throwing to him, so they had to make number 38. If you look at the PRD table, corresponds to start him. Let's look at a few more examples this month. Door town has a atomic number 83 If it emitted a have a particle, what is the daughter. No clear right it was from. So by balancing the mass number two sides, we get two or six. As the merest number off the doctor knew bliss 80 run has to be. It's at the make number, and this corresponds to Italian.

In this question, you will complete the nuclear equations and described the type of radiation. When completing the nuclear equation, you're simply making certain that the some of the mass number and atomic numbers are the same on both sides. So if this is what is provided in part a something plus 11 should give us 11. That would be zero and something plus five should give us six. So that would be one, something with no mass and a plus one charge would be a positron. So this is positron emission. For the next one we have sulfur 35 producing a beta particle. So zero plus something gives us 35. That would be 35 and minus one plus something gives us 16. So that would be 17 and 17 corresponds to the element chlorine because of this beta particle, this is beta emission. The next one we have something producing yatirim 90 plus a beta particle. So zero plus 90 should give us 90 and negative one plus 39 gives us 38 38 is strontium Because of the beta particle here, this is beta mission and for part D we have business to 10 with an atomic number of 83 producing an alpha particle, 84 2 is an alpha particle. So four plus something should give us to 10, that would be to six and two plus something should give us 83 that would be 81 81 is element Valium. And because of the alpha particle, this is alpha emission and for the last one we have something producing you trim 89 and a and a beta particle very similar to what we just did up here. But it's the atrium 90. So we're going to end up with strontium 89 instead of strontium 90. And this is still alpha mission. Mhm I'm sorry. This is beta mission because of the beta particle just like up here.

So for this question, they want us to completely nuclear equation. So in order to complete a nuclear equation, all we need to know is that some of the atomic number on both sides must be equal to each other. Any some of the atomic mass must be equal to each other. So when we look at the pr table, we see the B. I. Has an atomic number 83 P. O. Has an atomic number 84. Now we have 83 on the left of 84 on the right, the missing particles on the right. So we made the minus one on the bright side, minus one here. And we know we know that that is a beta particle. That's what you meant. You have to 14 on the left to 14 on the right, so this must be zero for part B, we have for protons uh forming an unknown into positron. Yeah. Right, so for d number atomic number, we have four protons. Each one has one. So that is four. And for the right side so far, I have to go in order to balance it out. We need to add to to the right side. Yeah. Put you here when we look at the period cable, we see that as HD alpha particle. As for the mass we have four on the left and we have zero on the right. We need to ask before we put a full here. Now for C we have E. S Xu 49 plus a new show on forming two neutrons plus an unknown plus G D 1 61. Now let's look at the atomic number. So we have for es that is 99 for G. D. That is 64. Now we have 99 on the left plus the zero from the neutron. And on the right we have zero from the neutrons plus 64. So we need to add 35 onto the right side for 35 here. And we see that that is B are roaming. Now ask for the mass. Mhm. Mhm. We have 2 49 on the left plus T one from neutron. We have two from the right from the neutron plus 1 61. And we need to add 87 to the right to balance it out. We put 87 there. Now for D. We have our en tu 22 20 forms and unknown plus an alpha particle. Now for the atomic number of R N. That is 86. So we put 86 on the bus on the right side, we have two from the alpha particle. So we need to add 84. Put 84 here and we see that that is pl polonium. Now ask for the mass. We have 2 20 on the left. We have four on the right swimming to add to 16. Now, for the last question we have G 68 plus an electron. Yeah. Uh huh. Their forms an unknown. So G. E. Has an atomic number of 32 to have 32 on the left minus the one from the electron. So that is 31. So we put 31 here. And for the symbol when we look at the parent table, we see that is G. A. For the mess. We have 68 on the left plus zero from the electron. 2068 on the right. Yeah.
