The immense number of carbon compounds (over 3 million) is due to two unique properties: A soft, layered hexagonal structure where each carbon

Carbon exists in different physical forms known as allotropes, which have different structures but the same chemical identity: Catenation Property of forming long chains or rings

They have weak intermolecular forces (Van der Waals forces), meaning they require less energy to change state.

Having a valency of four allows carbon to bond with four other atoms (of carbon or other elements like H, O, N, and halogens).

(Anion): It is extremely difficult for a small nucleus with only 6 protons to hold onto 10 electrons (6 original + 4 gained). Cannot form C4+cap C raised to the 4 plus power
