Chapter 2, Problem 13QAP

Interpretation Introduction

(a)

Interpretation:

The number of protons, neutrons, and electrons in a neutral atom of $\text{R}$ should be determined along with what element R represents.

Concept introduction:

The expression of isotope is given by: $\text{X}$

Where, X = element, A = mass number and Z = atomic number

The atomic number is equal to the number of protons of an element whereas sum of number of protons and number of neutrons is equal to mass number.

For neutral atom, number of protons is equal to the number of electrons.

Interpretation Introduction

(b)

Interpretation:

The number of protons, neutrons, and electrons in a neutral atom of $\text{T}$ should be determined along with what element T represents.

Concept introduction:

The expression of isotope is given by: $\text{X}$

Where, X = element, A = mass number and Z = atomic number

The atomic number is equal to the number of protons of an element whereas sum of number of protons and number of neutrons is equal to mass number.

For neutral atom, number of protons is equal to the number of electrons.
