Answer
Metals are good conductors of heat and electricity, they tend to lose electrons when they undergo chemical reactions, and they are shiny, malleable and ductile. Nonmetals are poor conductors of heat and electricity and they tend to lose electrons when they undergo chemical reactions. Metalloids have properties intermediate between those of metals and nonmetals. Many metalloids are semiconductors.
