Question

what is the difference between the physical state of metals and nonmetals at room temperature​

Answer 1

Answer:

a metal is a solid substance, usually hard, lustrous and opaque. On the other hand, a non-metals is a solid or gaseous material, in which the metallic properties are absent. The matter is a physical substance that occupies space and has mass.

Explanation:

Metals refers to the natural elements that are hard, shiny, opaque and dense. Non-metals implies those chemical substances that are soft, non-shiny, transparent and brittle.

Example metal non-metal

Nature Electropositive Electronegative

Structure Crystalline Amorphic

Physical State at room temperature Solid (except mercury and gallium) Solid or gas (except Bromine)

Density High density Low density

Appearance Lustrous Non-lustrous

Hardness Most metals are hard, except sodium. Most metals are soft, except diamond.

Malleability Malleable Non-malleable

Ductility Ductile Non-ductile

Sonorous Sonorous Non-sonorous

Conduction Good conductor of heat and electricity Poor conductor of heat and electricity

Melting and Boiling point Very high melting and boiling point. Low melting and boiling point.

Electrons 1 to 3 electrons in the outer shell. 4 to 8 electrons in the outer shell.

Oxygen React with oxygen and form basic oxides. React with oxygen and form acidic oxides.

Acid React with acids and produce hydrogen gas. Do not usually react with acids
