Group 6: ns2 np4 - 6 outer electrons Group 7: ns2np5 - 7 outer electrons

Work Step by Step

Group 7A elements only need 1 electron to achieve a noble gas configuration and have a full outer shell. Since group 6A elements need two electrons, their affinity for one electron is noted as less negative because one electron will only give them a np5 configuration - this is not the most stable form they can achieve. All atoms wish to fill their outer shells and achieve noble gas configuration.
