Chapter 2, Problem 2.38P

Interpretation Introduction

Interpretation:

The number of protons, neutrons and electrons in the atom of each $\text{F}$, $\text{N}$, and $\text{O}$ should be determined.

Concept Introduction:

Isotopes are the elements with same atomic number (same number of protons) and different mass number (due to different number of neutrons).

$\text{Mass number = Atomic number + number of neutrons}$

$\text{A= Z + N}$.
