Question

is metals positive and non metals negative?!

are acids non metallic in nature and bases metallic in nature?

are metals and non metals ( anion and cation ?!) what are they?

Answer 1

Metals can easily lose electron from their valence shell. So they form positive ions or cations.
eg. Na loses one electron to form Na+

Non-metals can easily accept electrons. So they form negative ions or anions.
eg. Cl can accept an electron to form Cl-

Metal ions are basic in nature and non-metallic ions are acidic in nature.
NaOH is a base whereas HCl is an acid.

Metals and non-metals are elements.
Metals cam form cations by losing electron and non-metals can form anions by gaining electron.
