A mole or Avogadro’s number, 6.022 x 10^23, is the number of carbon atoms in 12 grams of carbon. 1 mole = 6.022 x 10^23 = Avogadro’s number = the number of carbon atoms in 12 grams of carbon. Moles = Grams Atomic Weight Group 1: Alkali Metals Group 2: Alkaline Earth Metals Group VII: Halogens Group VIII: Noble Gasses Metals lose electrons to form positive ions. Characteristics include ductility, malleability, thermal and electrical conductivity and a characteristic luster. Metal atoms easily slide past each other allowing metals
