WebThe ionisation energies for the period 3 elements Na-Ar are shown below in the diagram. There are a few observations worth making: The general trend in ionisation energy across period 3 elements is that it increases with increasing nuclear charge. There are 2 "dips" in this trend, these are with the elements aluminium and sulfur. Webwhy does ease of ionization increase up group 7 As you go up group 7 ,the attractive pull of the nucleus on the electrons increase therefore making it easier to gain an electron …

WebGroup VII - Ease of Ionization. Ionization Energy Group VII: decreases down the group. If the outer valence electrons are not near to the nucleus it will not take as much energy to remove them. Therefore, the energy required to pull off the outermost electron will not be as high for the elements at the bottom of the group since there are more ...
