- 1as more e- are removed from an atom the amount of energy needed to remove the next e- from an increasingly + atom will always increase. WHY>strength of attraction between nucleus and outer e- increases as other e- are removed (causes decrease in atomic radius and the e- removed from closer to the nucleus)
- 2what can successive IE energies be used forfinding the group in which an element belongs
(there will always be a very large increase in IE when an e- is removed from a new principle energy level that is much closer to the nucleus) - 3successive IE always increases (PINI)proton / e- ratio - increases
ionic radius- decreases
nuclear attraction on outer e- - increases
IE - ALWAYS INCREASES (more energy needed) - 4every now and again there is a big jump in IEwhen we take an e- from a shell closer to the nucleus
- 5IT IS MORE DIFFICULT TO REMOVE AN E- FROM A MORE + IONsfoa
