How do metals and non-metals generally compare in their conduction of heat and electricity?
Metals are typically good conductors of both; non-metals are generally poor conductors.
How does the appearance of metals typically compare with that of solid non-metals?
Metals are often shiny; solid non-metals are usually dull.
How do the mechanical properties of metals typically compare with those of solid non-metals?
Metals are often strong and malleable; solid non-metals are usually brittle.
How do the melting and boiling points of metals generally compare with those of non-metals?
Metals usually have relatively high melting and boiling points; many non-metals have lower ones.
What do metals tend to do with electrons in reactions, and what ions result?
They tend to lose electrons, forming positive ions.
What do non-metals commonly do with electrons when forming substances?
They commonly gain electrons to form negative ions or share electrons in covalent substances. They do not form positive ions.
