Question

Cual es la cofiguracion electronica de z=72 z=99 z=42 z=46 porfavor es urgente

Answer 1

z=72, 1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 3d^10 4p^6 5^s2 4d^10 5p^6 6s^2 4f^14 5d^2
z=99, 1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 3d^10 4p^6 5^s2 4d^10 5p^6 6s^2 4f^14 5d^10 6p^6 7s^2 5f^2
z=42, 1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 3d^10 4p^6 5^s2 4d^4
z=46,1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 3d^10 4p^6 5^s2 4d^6
