Question

Explain Metals and non - Metals​

Answer 1

Explanation:

Metals form basic oxides

Non metals form acidic oxides

Metals are sonorous

Non metals are not sonorous

Answer 2

Explanation:

METALS

With the exception of hydrogen, all elements that form positive ions by losing electrons during chemical reactions are called metals. Thus metals are electropositive elements with relatively low ionization energies. They are characterized by bright luster, hardness, ability to resonate sound and are excellent conductors of heat and electricity. Metals are solids under normal conditions except for Mercury.

NON-METALS

Elements that tend to gain electrons to form anions during chemical reactions are called non-metals. These are electronegative elements with high ionization energies. They are non-lustrous, brittle and poor conductors of heat and electricity (except graphite). Non-metals can be gases, liquids or solids.
