Chapter 4, Problem 60A

Interpretation Introduction

Interpretation : The number and kinds of subatomic particles in boron-11 are to be described.

Concept Introduction : Subatomic particles are the fundamental particles formed by the breaking of atoms into smaller units. The nucleus is a tiny particle that contains protons and neutrons.

Answer to Problem 60A

There are 5 protons and 6 neutrons that are found in the nucleus while the 5 electrons revolve around the nucleus.

Explanation of Solution

Subatomic particles are the fundamental particles formed by the breaking of atoms into smaller units.

Protons, neutrons, and electrons are the three different types of subatomic particles.

Since the given element is boron-11, the mass of the element is 11.

The boron element has 5 protons, 5 electrons, and 6 neutrons.

Looking down into the nucleus, there are 5 protons and 6 neutrons present.

Looking out from the nucleus, 5 electrons are revolving around the nucleus.
