What is a molecule
a group of atoms bonded together, representing the smallest fundamental unit of a chemical compound that can take part in a chemical reaction.

What is a covalent bond
A covalent bond, also called a molecular bond, is a chemical bond that involves the sharing of electron pairs between atoms. These electron pairs are known as shared pairs or bonding pairs.
What is a chemical bond
A chemical bond is a lasting attraction between atoms, ions or molecules that enables the formation of chemical compounds
What is covalent bonding
The stable balance of attractive and repulsive forces between atoms, when they share electrons, is known as covalent bonding
What is an anion
A negatively charged ion, the opposite of cation
What is a cation
A positively charged ion, the opposite of anion
What is an ion
An atom or molecule with a net electric charge due to loss or gain of one or more electrons
