Answer 2

ground state: 1s^2 2s^2 2p^6 3s^2 3p^6 3d^10 4s^2 4p^3

Answer 3

But idk the excited state

Answer 4

Answer 5

Chemistry is my worse subject. Promise.

Answer 6

Sorry to disappoint you.

Answer 7

Answer 8

usually in the excited state, one or more of the s-electrons jump into the next p-level

Answer 9

so how would i write it?

Answer 10

You need to move the 3d level, but the ground state ends in \(4s^23d^{10}4p^3\), so move one of the s-electrons into the p-level

Answer 11

so it'd be 4s3d^104p^4

Answer 12

when writing electron configurations, always put the '1' superscript, so it would be \(4s^13d^{10}4p^4\), but yes
