Question

Determine the Electron Configurations for the following elements.

Chlorine 17:
Bromine 35:
Tantalum 73:
Iron 26:
Oxygen O2-:
Iron Fe3+:

Answer 1

Answer:

chlorine 17 : 1s^2 2s^2 2p^6 3s^2 3p^5

Bromine 35 : 1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 3d^10 4p^5

tantalum 73: [xe] 4f^14 5d^3

iron 26 : 2 8 8 8

Explanation:

hope it helps and oxygen O2- and iron Fe3+ sry but i don't remember

Answer 2

Answer:

Normal Electronic COnfig.

Cl- 2,8,7

Bromine-2, 8, 18, 7

Tantalum - 2, 8, 18, 32, 11, 2

Iron- 2, 8, 14, 2

O2- = 2, 6

Iron Fe 3+ = 2, 8, 13

Subshell EC of Elements

Cl = 1s2,2s2,2p6,3s2,3p5

Br = 1s2,2s2,2p6,3s2,3p6,4s2,3d10,4p5.

Tantalum = Xe 4f14,5d3,6s2

Iron = [Ar] 3d6 4s2

O 2- = 1s2,2s2,2p2

Iron Fe 3+ = [Ar] 3d5
