Solution Metals: High to moderately electropositive so electrons are generally free moving. Good conductors of heat and electricity. Non-metals: Moderately to highly electronegative so no free electrons. Bad conductors of heat and electricity.
WebAug 20, 2024 · 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. Physical Properties of Nonmetals
