Is aluminium a metal or metalloid?
Its crystalline structure shows some evidence of directional bonding. Aluminium bonds covalently in most compounds. The oxide $ce{Al2O3}$ is amphoteric, and a conditional glass-former. Aluminium can form anionic aluminates, such behaviour being considered nonmetallic in character. The line between metals and non-metals is somewhat arbitrary with
