what is the electron configuration of chlorine (cl)? 1s²2s²2p⁶3s²3p³ 1s²2s²2p⁶3s²3p⁵ 1s²2s²2p⁶3s²4s²3p³…

Brief Explanations:

Chlorine has an atomic number of 17. Electrons fill orbitals in the order 1s, 2s, 2p, 3s, 3p etc. The 1s orbital holds 2 electrons, 2s holds 2, 2p holds 6, 3s holds 2 and 3p holds 5 to make a total of 17 electrons.

Answer:

1s²2s²2p⁶3s²3p⁵
