Covelant bonding
A stable electron configuration is created by sharing of electrons between neighbouring atoms
Covelant molecule
A covalent bond is a chemical bond that involves the sharing of electrons to form electron pairs between atoms.
metaloid

properties of non metals
not ductile
poor conductors of heat and electricity
not lustrous
