Metals are found in the left most part (except Hydrogen) and in the middle of the periodic table. Metalloids are found in Group IIIA, starting from Boron, then followed by a zigzag pattern: Silicon, Germanium, Astatine, Antimony, etc. Nonmetals are found in the right most part of the periodic table, starting from Group IVA.
