Chapter 4, Problem 87E

Interpretation Introduction

Interpretation:

The atomic number and mass number are to be calculated for each of the given isotopes.

Concept Introduction:

The number of protons that are present in the nucleus of an atom is called its

atomic number.

The symbol for an atomic number of an atom is $\text{Z}$.

The elements in the periodic table are listed according to the atomic numbers.

The mass number $\left(\text{A}\right)$ is calculated as follows:

$\text{A}=\#\text{n}+\text{Z}$

Here, $\#\text{n}$ is number of neutrons.
