It may be the Aufbau Principle if you are looking for specifics. or just an electron configuration with 1s, 2s, 2p, 3s, 3p, 3d, etc.
The order for filling in the sublevels becomes; 1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 5s, 4d, 5p, 6s, 4f, 5d, 6p, 7s, 5f, 6d,7p.
2d is invalid. Only s and p orbitals in 2nd energy level
If you mean "electron configuration" then: Long-hand version: 1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 3d^10 4p^6 5s^2 Short-hand version: [Kr] 5s^2 Note: The "^" symbol means the the following number is in the form of a superscript.
4p+2 = 3p-7 4p-3p = -7-2 p = -9
simply add the like terms: 4p -3p +2q -2q = p
1s 2s 3s 3p 4s 3d 4p
4p+7q
4p + 9 + (-7p) + 2 = 4p - 7p + 9 + 2 = -3p + 11

4p+9-7p+2 -3p+11 p = 11/3
11-3p
3p+5+p = -23 3p+p = -23-5 4p = -28 p = -7
ms = -1/2
p+2 = 2-3p p+3p = 2-2 4p = 0 p = 0
