I can explain chemical bonding in terms of the transfer or sharing of electrons.
Muuji qoraalka
There are five different types of substance: monatomic, simple covalent (molecules), giant covalent, ionic and metallic.
The outer shell in most atoms can hold 8 electrons but, in hydrogen and helium, it can only hold 2 electrons.
Most atoms increase their stability by forming bonds with other atoms so that they have a full outer shell of electrons.
Some atoms will share electrons with other atoms to increase their stability.
Some atoms will lose or gain electrons to increase stability forming cations or anions, respectfully.
