There are a few different ways to answer this question. The most efficient way of writing it would be: [Ne] 3s1. This is because typically, electron configuration is done short hand by using the closest noble gas (without using one larger than the atom).
However, breaking that down, sodium is really: 1s2 2s2 2p6 3s1. Fortunately that is sequential in both energy level and orbital level, but you should remember that in energy level the sequence is 1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 5s, 4d, 5p, 6s, 4f, 5d, 6p, 7s, etc., but in orbital level the sequence is the predictable 1s, 2s, 2p, 3s, 3p, 3d, 4s, 4p, 4d, 4f, 5s, 5p, 5d, 5f, etc.
