How are metals and non metals different?

Answer 1

Metals lose electrons easily, and non-metals gain electrons easily. Metals are ductile; which means they can be stretched out into wire, and non-metals are nonductile.
Metals differ from nonmetals merely in that they have a positive oxidation number. An element's oxidation number will be it's charge when it is ionized. For example when sodium (Na) is ionized it will lose 1 electron (to have a complete valance shell) losing this electron (a negative particle) will cause the atom to have a positive charge (and therefore a positive oxidation number too) Non metals will have negative oxidation numbers. When a non metal is ionized it will gain electrons (if it has more than four electrons in it's valence shell gaining electrons takes less energy) when it gains these negative particles it gains a negative charge. The oxidation number is determined by how many electrons are in the valence shell of an electrically neutral atom. Any less than four and the oxidation number is positive so you have a metal, more than four you have a non metal.

Answer 2

The reactivity of metal is based on the chemical compounds that combine to create the fibres that make up metal. The complex chemical basis of each specific specimen varies according to the standard and variety of metal. The reactivity of each category of metal relys entirely on what comes together to make it, and which substances or objects you use with it.

Answer 3

Metals are typically shiny, good conductors of electricity and heat, malleable, and ductile, while non-metals are generally dull in appearance, poor conductors of electricity and heat, brittle, and not malleable or ductile. Additionally, metals tend to form positively charged ions, while non-metals tend to form negatively charged ions or share electrons in covalent bonds.
