A description and practice of finding metals, nonmetals, and metalloids on the Periodic Table.
In general metals are found on the left-hand side of the periodic table. Nonmetals are found on the right-hand side. Between them are the metalloids.
Note that Hydrogen (H) is an exception. It is a nonmetal but is found on the left-hand side of the Periodic Table. This is because it has one valence electrons in its outer shell like the other elements in Group 1, but it has physical and chemical characteristics of nonmetals.
