What is the difference between a metal and a non-metal?

Back

Metals are typically shiny, malleable, and good conductors of heat and electricity, while non-metals are usually dull, brittle, and poor conductors.

Front

What is the octet rule?

Back

The octet rule states that atoms tend to gain, lose, or share electrons to achieve a full outer shell of eight electrons.
