Textbook Problem

# Complete the following nuclear equations. Write the mass number, atomic number, and symbol for the remaining particle. (a) 47 111 Ag    →   48 111 Cd   +   ?   (b) 36 87 Kr    →   -1 0 β   +   ?   (c) 91 231 Pa    →   89 237 Ac   +   ?   (d) 90 230 Th    →   2 4 He   +   ?   (e) 35 82 Br    →   36 82 Kr   +   ?   (f) ?   →   12 24 Mg   +  -1 0   β

(a)

Interpretation Introduction

Interpretation:

Given nuclear equation has to be completed and then the mass number, atomic number, and symbol for the remaining particle should be determined.

Concept Introduction:

Nuclear reaction is a physical process in which there is a change in identity of an atomic nucleus. Natural radioactive decays, artificial radioactive decays... are considered as nuclear reactions because these processes make changes in the identity of an atomic nucleus.

Common particles in radioactive decay and nuclear transformations are mentioned below,

Explanation

Given incomplete nuclear reaction is,

47111Ag48111Cd+?

47111Ag Undergoes nuclear reaction, producing 48111Cd; there is no changes in products and reactant’s mass number while the atomic number is increased by one
