Chapter 2, Problem 24QP

Interpretation Introduction

Interpretation:

The appropriate symbols for the given isotopes are to be represented.

Concept introduction:

Protons are the positively charged particles present in the nucleus of an atom.

Neutrons are electrically neutral particles having a mass slightly greater than protons. They are also present in the nucleus of an atom.

The atomic number (Z) of an atom is defined as the number of protons present inside the nucleus.

$Z=p$, where p is number of protons

The mass number (A) of an atom is defined as the number of neutrons and protons present inside the nucleus.

$A=n+p$, where p is number of protons and n = number of neutrons
