Chapters 7&8

What is Isoelectronic? When 2 ions and/or elements have the same electronic configuration
Octet Rule 8e- in the outer shell of an atom; most stable state of an atom
Cations (+) charged ions; smaller than the parent element because loses e- shell
Anions (-) charged ions; larger in size than the parent atom because protons in the nucleus cannot hold the extra electrons closely
Ionization Potential (kJ/mol) Amount of energy required to remove one e- from an atom - (+) values - usually endothermic - the lower the IP, the more reactive
Electron Affinity Energy associated when an atom gains an e- usually (-) values - Exothermic
Frequency # of waves that pass a point per second (Hz)
Wavelength nm - 1nm=3*10^-9m
Plank's Constant h= 6.626*10^-34 J*s
Speed of Light c= 3*10^8 m/s
