Answer:
A - Have no overall electric charge
Explanation:
Ideally, atoms of elements are chemically bonded to form molecules. A molecule is said to be a SIMPLE MOLECULE if it contains only a few atoms linked strongly together by covalent bonding. Examples of simple molecules are O2, CO2, I2, Cl2 etc.
The following properties are possessed by simple molecules:
- They have no overall electric charge
- They have low melting and boiling points due to the weak intermolecular forces that are easily overcomed when temperature is applied.
- Since they have no net charge, they do not conduct electricity.
- As their name implies, they rather have simple structures.
