Exam 2 Periodic trends -Ionization energy-energy required to remove an electron and pull it away an infinite distance -always positive for neutral atoms -becomes more positive across a period or up a group -S<P because P has extra stability due to half filled p-orbital -electron affinity-energy required to add an electron -negative -more negative across the period (bigger) or up a group -N is an exception ex. rank least to most negative affinity Al, P, Si, S, Cl
