In the ground state of krypton (atomic number 36), the electron configuration is 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d¹⁰ 4p⁶. Krypton has completely filled sublevels in the 1s, 2s, 2p, 3s, 3p, 4s, 3d, and 4p orbitals. This totals to eight completely filled sublevels.

In argon (atomic number 18), the 3rd energy level has the 3s and 3p sublevels filled, with the electron configuration ending in 3s² 3p⁶. In krypton (atomic number 36), the 3rd energy level also has the 3s and 3p sublevels filled, but it additionally fills the 4s and 3d sublevels, resulting in an electron configuration of 4s² 3d¹⁰ 4p⁶.
The orbital designation "4p 3s 2d 5f" is invalid because it does not follow the proper order of filling orbitals according to the Aufbau principle. The correct order is 1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 5s, 4d, 5p, 6s, 4f, 5d, 6p, 7s, 5f, 6d, and 7p.
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.
4p+2 = 3p-7 4p-3p = -7-2 p = -9

simply add the like terms: 4p -3p +2q -2q = p
4p + 9 + (-7p) + 2 = 4p - 7p + 9 + 2 = -3p + 11

No, the electron configuration 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 4d¹04p⁵ is not valid because it incorrectly suggests that the 4d subshell is filled before the 4p subshell. In the correct order of filling, the 4p subshell would be filled after the 4s and 3d subshells, so the proper configuration for an element with atomic number 35 (bromine) is 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d¹⁰ 4p⁵.
