Physical Properties
in general, the physical properties of nonmetals are opposite to those that characterize the metals
most nonmetals are dull, solid nonmetals are brittle, lower densities
Compounds of Nonmetals
when nonmetals and metals react, valence electrons move from the metal atoms to the nonmetal atoms
