Explanation:
metal
a solid material which is typically hard, shiny, malleable, fusible, and ductile, with good electrical and thermal conductivity (e.g. iron, gold, silver, and aluminium, and alloys such as steel).
non metal.
In chemistry, a nonmetal is a type of chemical element generally characterized by low density, low strength, and a tendency to form acidic compounds
metalloid
an element (e.g. arsenic, antimony, or tin) whose properties are intermediate between those of metals and solid non-metals or semiconductors. Also called semimetal.
