Explain the following:
What are the properties of metals and Non-metals?

Explanation

i.Physical properties of metals:
a. They are ductile and malleable, b. They are good conductors of heat and electricity, c. They are lustrous, d. They are sonorous, e. They are hard ( except lithium, sodium, potassium), f. They have high melting and boiling points (except sodium, potassium mercury, gallium).
ii. Physical properties of nonmetals:
a. They are either solid or gas at room temperature (except bromine), b. They are generally non-lustrous (except iodine, diamond), c. They are bad conductors of heat and electricity ( except graphite), d. They are generally soft (except diamond), e. They have low melting and boiling points
