Ionization Energy - Answer-energy required to remove an electron from an atom in the gas phase Left Side Electrons - Answer-have weaker attractions to remove electrons *easier to remove electrons from the left side of the table than the right side* Does it take MORE or LESS energy to remove an electron from Li than from Na? - Answer-MORE Why? Because as we move down a group, the orbitals become larger and weaker. While going across the effective nuclear charge increases. (holds onto the ele...

temperature is related to KE how? temp is the average kinetic energy thermal energy is related to KE how? thermal energy is the total KE Brainpower enthalpy of fusion is ALWAYS greater than enthalpy of vaporization because? it has to break more bonds (solid --> liquid) the amount of heat depends on (2 factors) 1. the type of substance 2. the amount of the substance during a phase change does temperature change? NO if an archaebacerial species lives in a pool that is 0.01 M HCL wh...
