Changes

'''Metals''' are shiny, [[solid]], and [[conductive]] substances, such as [[iron]]. They contrast with the [[nonmetal]]s. They are found on the left side of the [[periodic table of the elements|periodic table]]. Most [[elements]] are metals. Some metals are very strong and light, like [[aluminium]]. Others are soft and heavy, like [[lead]]. The rare earth metals have to be stored in oil because they oxidize explosively when they come into contact with water, even water vapor in the air.
