What is the electron configuration for alluminum?

Answer 1

1s2 2s2 2p6 3s2 3p1

3s23p1

2nd answer :

outer electron configuration is the same as valence electron , you can easily find it in the period table : using the number of the group :

Group 1 : one, Group 2 :two , Group 3-12 cannot be found instead d electron count is used , group 13 : three , Group 14 : four ans so on until Gruop 18 : Eight

Answer 2

The electron configuration for aluminum is 1s^2 2s^2 2p^6 3s^2 3p^1. This means that aluminum has 13 electrons, with two in the 1s orbital, eight in the 2s and 2p orbitals, and three in the 3s and 3p orbitals.

Answer 3

2,8,3 or 1s2 2s2 2p6 3s2 3p1 or [Ne] 3s2 3p1
