Metals and metalloids :)))

Well metals are good conductors of heat and electricity because in a storm you don't wanna be by metal or holding metal in the air because the lighting can strike it at any moment, plus when we plug something in we see a metal piece going into the socket, and because we use pots and pans to bake and cook food so they would be good conductors of heat because if you take them out with your bare hands your hands will get Burt because its metal.

Hope that helped!
