Question

differences between metals and nonmetals with exceptions

Answer 1

Metals, except mercury & gallium are solids at room temperature while non-metals , except bromine are solids or gases at room temperature.

Metals are malleable and ductile while non-metals are non-malleable & non-ductile

Metals are lustrous while non-metals, except diamond & graphite which are allotropes of carbon as well as iodine, are non-lustrous.

Metals are good conductors of heat & electricity. Exception: Lead & mercury are poor conductors of heat. Non-metals are poor conductors of heat and electricity. Exception: Graphite conducts electricity.

Metals except Na & K have high melting & boiling points while non-metals except diamond have low melting and boiling points.

Metals except Na & K are hard while non-metals except diamond are soft.

Answer 2

Answer:

Physical properties of metals

Explanation:

Physical properties make them useful for many purposes for example copper is used in making electric wires, gold is used to make pots, pan. Metals react with nonmetals to form ironic bonds for example copper is used as wiring as it is good conductor of electricity metals have high melting points and high boiling points as the strong metallic bonds metals are good conductor of electricity which means that they can conduct electricity all metals are physically lecturers they have a luster that makes them Shine.Gold is used for jewellery.
