Chapter 3, Problem 63E

Interpretation Introduction

Interpretation:

The connection between the properties of elements and atoms that composed it, is to be explained.

Concept Introduction:

 An atom is the smallest particle capable of independent existence. All atoms are composed of the same subatomic particles i.e., electrons, protons, and neutrons.

 Atoms of different elements have different physical and chemical properties. This is because of the difference in their number of electrons.

 Atoms are present in both living and nonliving things with the difference that, in living things, atoms have combined to form molecules, which have then aggregated to form cells.
