Chem 109 Periodic Trends “You’ve been taken, but you don’t know it yet” – N.W.O. - Ministry Atomic Size List the elements from smallest to largest: Br, Cl, F, I F Cl Br I as “n” increases, size increases List these elements from smallest to larget: In, Rb, Sn, and Sr Sn In Sr Rb as Z eff decreases, size decreases Ionization Energies List these elements from lowest IE to highest: Ba, Ca, Mg, Sr Ba Sr Ca Mg as n decreases, IE increases Why is the IE 2 always higher than IE 1 ? Because IE 2 pulls an electron away that is closer to the nucleus
