Explanation:
<u>metal</u>
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).
<u>non metal.</u>
In chemistry, a nonmetal is a type of chemical element generally characterized by low density, low strength, and a tendency to form acidic compounds
<u>metalloid</u>
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.
