219/86 Rn→ 215/84 Po+ AlphaThe nuclear equation shows the transmutation of a form of radon into polonium and an alpha particle. In one to two sentences, explain whether or not the reaction is balanced.
a.An alpha particle has 2 protons and 4 neutrons
b.An alpha particle has 2 protons and neutrons
c.An alpha particle has 3 protons and 3 neutrons
d.An alpha particle has 4 protons and 4 neutrons

219/86 Rn + Beta→ 219/85 AsThe nuclear equation shows a form of radon into astatine and a beta particle. In one to two sentences, explain whether or not the reaction is balanced.
a.mass number is zero, it is a proton
b.mass number is zero, and it is a neutron
c.mass of beta is zero, and it is an electron
d.mass number is zero, it is a gamma.

Nuclear reactions can be written out in equation form with information about the nuclei that take place in the fusion reaction and the nuclei that are produced. Choose 2 answer choices below that best explain how you would identify the reaction as fusion.(2 points)
1.one or more nuclei must be coming together on the right side of the reaction
2.The largest number is present on the right side of the reaction
3.The largest mass number is present on the left side
4.There will be a nucleus with a large number of protons on the right side of the reaction

10/6 C→ 10/5 B + 0+1 eA student claims that the equation models beta-minus decay because the atomic number of the nucleus decreases by one. In one or two sentences, explain the error in the student’s reasoning.
1.This equation models a beta plus decay
2.The equation models a beta-minus
3.The student is incorrect because in beta-minus decay, the atomic number of the nucleus increases by one
4.The student is correct
