Which neutral element has the following electron configuration? 1 s^2 2s^2 2 p^6 3 s^2 3 p^41s ​2 ​​ 2s ​2 ​​ 2p ​6 ​​ 3s ​2 ​​ 3p ​4 ​​

Answer 1

A neutral chlorine atom has an electron configuration of 1s²2s²2p⁶3s²3p⁵.

Step-by-step explanation:

A neutral chlorine atom has 17 electrons. Two electrons can go into the 1s subshell, 2 can go into the 2s subshell, and 6 can go into the 2p subshell. That leaves 7 electrons. Of those 7 electrons, 2 can go into the 3s subshell, and the remaining 5 electrons can go into the 3p subshell. Thus, the electron configuration of neutral chlorine atoms is 1s²2s²2p⁶3s²3p⁵.
