Topic 1
An atom is the smallest particle of an element. A molecule is a particle that can exist independently and contains one or more atoms.
Topic 2
A radical is an atom or group of atoms acting as a charged unit. Atomicity is the number of atoms in a molecule.
Topic 3
The first twenty elements are commonly used to build chemical names, symbols, formulae, and valency patterns.
Topic 4
Valency is the combining capacity of an element or radical. It helps in writing correct chemical formulae.
