What distinguishes metal and non-metal?

Answer 1

Metals typically have the following physical properties: a lustrous appearance, the ability to change shape without breaking, and excellent conductivity of heat and electricity. Nonmetals typically do not have these physical properties, although there are some exceptions. However it is the chemical difference that really counts. Metals tend to lose electrons to form positive ions, and nonmetals tend to gain electrons to form negative ions.

Answer 2

Metals are found to the left of the stair-step line on the Periodic Table, and non-metals are to the right (not including metalloids touching the line). Metals are have more luster, are better conductors, and generally are very durable. Nom-metals are generally dull, oftentimes gaseous, terrible conductors, and not so durable. Metals form positive ions, and non-metals form negative ions.

Answer 3

Yes. For example, metals tend to have luster, are ductile and malleable, and are good conductors of heat and electricity. Nonmetals tend to be dull, are brittle, and are poor conductors of heat and electricity.

Answer 4

Metals form cations, nonmetals form anions.
