Explain the connection between the properties of an element and the atoms that compose it.

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.

Explanation of Solution

An element is composed of an atom. Physical and chemical properties of an atom are functions of its valence electrons. Atoms make up elements and so...
