Question

Nuclear reactions involve a change in the nucleus of an atom. For this reason, nuclear equations show the mass number and atomic number of each species. Nuclear equations must be balanced in both mass number (mass balance) and atomic number (charge balance). For example, consider the equation for the decay of carbon-14:

14 6C?14 7N+ 0?1e

Part A:

Write the identity of the missing particle for the following nuclear decay reaction:

60 27Co?60 28Ni+?

Express your answer as an isotope.

Part B:

Write the identity of the missing nucleus for the following nuclear decay reaction:

224 88Ra?4 2He+?

Express your answer as an isotope.

Part C:

Write the identity of the missing nucleus for the following nuclear decay reaction:

??8 4Be+0 1e

Express your answer as an isotope.

Explanation / Answer

part A :- 60 27 Co => 60 28 Ni+ + 0-1e

same mass = product side as well as reactant side

for charge balance 1 e is to be added in product side

part B :- 224 88 Ra => 4 2 He + 220 86 Ra

part C :- 8 3 Li => 8 4Be + 0 1e
