Electron configurations of noble gases

Postby Joshua Xian 1D » Thu Nov 02, 2017 12:31 pm

For writing out the electron configuration of noble gases (and ions that have the same electron configurations as noble gases), can we just put the shorthand (e.g. for neon, [Ne]) or do we need to write out the electron configuration from the previous noble gas (e.g. for neon [He]2s2 2p6), or are both correct?

Both are technically correct, but the reason we usually write it the second way (neon = [He]2s2 2p6) is so that we can see how many valence electrons are in the outermost shell.
