What is the noble gas notation for Neon?

This is a little uncommon, since Neon is itself a noble gas, but not at all unheard of, since the only noble gas that does not have a noble gas shorthand notation is Helieum, #"He"#.

Since #"Ne"# is in group 18, row 2 of the periodic table, it has an atomic number of 10, which means its electron configuration must account for 10 electrons.

#"Ne":1s^(2)2s^(2)2p^(6)#

Using the electron configuration of #"He"#, the closest noble gas that comes before #"Ne"# in the periodic table, we can write the noble gas shorthand notation for #"Ne"# like this:

#"Ne":["He"]2s^(2)2p^(6)#
