Non metal= hydrogen, oxygen, iodine, carbon, bromine chlorine, etc.
Answer:
Explanation:
non metals are the things which are not metals. non metals have relatively low density ,low melting point and low boiling point and also low density.
A nonmetal possesses very poor thermal conductivity and electrical conductivity. Nonmetals have relatively high ionization energy, electronegativity and electron affinity,
carbon ,nytrogen and oxygen are non metals
alkali and alkaline are metals and they have higher bowling , melting points and density
In periodic table metals are shown at the left and in the middle of the table such as zr , Nb,Ca,Mg etc.
on the upper right corner of periodic table non metals are found such that He, O,Cl etc.
