Non-metals are also called electronegative elements because the non-metal atom form negatively charged ion by accepting electrons.
1. Reaction of Non-metals with Oxygen
All non-metals react with oxygen to form acidic or neutral oxides. For example, Carbon forms acidic carbon dioxide on reacting with oxygen.
C+ O2 → CO2
( Carbon Dioxide)
2. Reaction of Non-metals with Water
Non-metals do not react with water.
3. Reaction of Non-metals with Dilute Acids
Non-metals do not react with dilute acids and don’t displace hydrogen from dilute acids, because non-metals are electron acceptor. So, they cannot supply electrons to H+ ions. So, they do not displace hydrogen from dilute acids.
4. Reaction of Non-metals with Chlorine
Non-metals react with chlorine to form covalent chlorides. For example,
H2 + Cl2 →2HCl ( Hydrogen chloride)

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 orsolids.
