Write some chemical properties of non metals

Reaction with air: non metals react with air to form non metallic oxides acidic oxides. These oxides turn blue litmus red
ii. reaction with hydrogen: non metals like nitrogen carbon and phosphorus react with hydrogen to form different compounds
iii. reaction with acids: some non metals react with acids to form corresponding oxy-acids
iv. Reaction with non metals: non metals react with other non metal element form their corresponding compounds
v. reaction with basic oxides: non metals like carbon react with basic oxides to reduce them to metal and carbon monoxide
