Detailed Solution

Part (a):

The average mass of an element's atom, as compared to 1/12th the mass of one carbon-12 atom, is known as relative atomic mass.

Part (b):

An atomic mass unit is a unit of mass equal to one twelfth of the mass of a carbon-12 atom.

Part (c):

A positively or negatively charged atom, group, or atom is known as an ion.

Part (d):

Ionic compounds are made up of positively charged cations and negatively charged anions making it a neutral compound.

Part (e):

Atomicity refers to the total number of atoms in a molecule.
