Chapter 2, Problem 2.65AP

Interpretation Introduction

Interpretation:

The neutral atoms of two different elements can have same number of electrons.  This statement has to be explained.

Concept Introduction:

Electrons:

Electrons have an electric charge of $\text{-1}$, which is equal but opposite to the charge of a proton, which have an electric charge of $\text{+1}\text{.}$  All atoms have the same number of electrons as protons, so the positive and negative charges cancel out making atoms electrically neutral.
