metals combine with nonmetals

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

Dihydrogen reacts with non-metals under specific conditions. Some of the reactions are: The reactivity of halogen towards dihydrogen decreases as: F 2 > Cl 2 > Br 2 > I 2 As a result, fluorine reacts in dark, chlorine in the presence of sunlight, bromine reacts only upon heating whi..

They are generally non-lustrous, brittle, poor conductors of heat and electricity. For example: Sulphur, phosphorus, nitrogen e..
