Answer
Two chemical properties that distinguish a metal from a nonmetal are :
1. Metals form basic oxides while Non-metals form acidic oxides or neutral oxides.
2. They have 1, 2 or 3 electrons in the valence shell. So they can lose electrons easily while Nonmetals own more than 4 electrons in their valence shell. So they can easily gain electrons.
Two physical properties that distinguish a metal from a nonmetal are :
1. Metals are lustrous while Non-metals are non-lustrous.
2. Metals are good conductors of heat and electricity while Non-metals are poor conductors of heat and electricity.(except graphite which is a good conductors of electricity).
