Describe how the first four ionization energies of aluminium vary.
Hey hey cousin ITT!!! the first 4 ionisation energies are 1st 577.6 2nd 1816.6 3rd 2744.7 4th 11,577 [Ne].3s2.3p1 so you have 3 shells.to remove the first 3 electrons the energies to not have much difference between them but to get into the next shell with 8 electrons when the atom is happy and stable .it will require alot more energy so the next shell 2s2.2p6 thats where the jump of energy would be as we can see there are 8 electrons and dont want to be disturbed Between the 3rd and 4th there seems to be a larger jump in energy needed to remove the next electronBetween the 1st and 3rd ionisation 'step' it's almost doubling can you see? :-) then between 3rd and 4th step it more than doublesReasons that you can take from the data is that the electrons after the 3rd step require more energy because the electron is nearer to the nucleus therefore the force of attraction between the electron and nucleus is much greaterIt gets more difficult for atoms to loose their electrons due to the progressive positive charge on electron ionshope this helps good luck!! ;-)
