Chapter 8, Problem 101A

Interpretation Introduction

Interpretation: The two subatomic particles which are equal in a neutral atom are to be determined.

Concept introduction:

Atoms, which are minuscule bits of matter, are what distinguish each chemical element from the others. A negatively charged central nucleus and orbiting negatively charged electrons make up an atom. The nucleus is made up of positively charged, relatively massive protons and neutrons.

Answer to Problem 101A

Electrons and protons

Explanation of Solution

Protons and neutrons reside in the nucleus while electrons revolve around it. Protons are positively charged, electrons are negatively charged, and neutrons are neutral. In a neutral atom, no. of positively charged and negatively charged subatomic particles should be equal.

Thus, in a neutral atom, no. of protons and neutrons should be equal.
