What is the electron configuration for sodium (Na)?

Answer by  jsmith (2067)

The electron configuration for sodium is 2,8,1 electrons per shell. The periodic table tells you there are 11 electrons, then you just distribute them 2,8,18,32,18 etc.

In a sodium atom, there are two electrons in the most inner shell, eight in the second inner shell. The outer shell has one electron only. It is because it belongs to the Group 1(hydrogen and alkaline metals) in the periodic table. The electron configuration of sodium (Na) is 2,8,1.

Answer by  Aral (184)

The electron configuration is 1 s2,2 s2, 2p6, 3 s1. Direct information about electron configurations isn't generally listed on periodic tables, though it is implied by the table's structure.

Answer by  Bostongal1 (54)

Since sodium has 11 electrons, it fills in the first two shells with 2 and 8 electrons respectively, leaving 1 electron in the outermost shell.
