Question | Answer |
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 |
