Isotopes - Same number of protons and electrons but different number of neutrons. Therefore, different mass. Ex: N=18 A=18+17=35 => Cl-35 N=20 A=20+17=35 =>Cl-37 Relative mass=Atomic Mass - Weighted avg= sum(mass of isotope)(fraction of atoms) Ex: Chlorine 3/4 are Cl-35, 1/4 are Cl-37 Atomic Mass=(35*.75)+(37*.25)=35.5 Identify - Alkali metals (H not alkali metal) Alkaline earth metals Transition metals Triels/Icosagens: boron group Tetrels/Crystallogens: carbon group
