Chapter 4, Problem 46A

Interpretation Introduction

Interpretation : The subatomic particles located in the nucleus in the Rutherford atomic model are to be explained.

Concept Introduction : Rutherford performed a gold foil experiment to test the atomic structure plum-pudding model. The plum-pudding model of atomic structure was described by Thomson who discovered electrons.

Answer to Problem 46A

The subatomic particles located in the nucleus in the Rutherford atomic model are protons and neutrons.

Explanation of Solution

To describe the structure of atoms, Rutherford performed a gold foil experiment.

He overcame the failures that occurred in a plum-pudding model of atomic structure.

A new atomic theory was proposed by Rutherford depending on his experimental results.

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.

The tiny, inner core of an atom known as the nucleus is made up of protons and neutrons.

The term "nuclear atom" refers to the Rutherford atomic model.

Protons and neutrons are found in the positively charged nucleus of the nuclear atom.

Nearly the whole volume of the atom is made up of electrons, which are scattered all around the nucleus.
