WebIn this table, you can see that helium has a full valence shell, with two electrons in its first and only, 1n, shell. Similarly, neon has a complete outer 2n shell containing eight … WebThe valence electron essentially experiences the potential from only one of the helium protons. The net result is that the 2p level for the helium valence electron is split. One of the two split states is 0.22 eV lower …
