Electron Configuration and the Periodic Table
Which of the following is the condensed electron configuration for chlorine?
17 electrons
1. [Ne]3p7
2. [Ne]3s23p5
3. [Ne]3s23p6
4. [Ne]3s23d5
5. [Ne]3s23p33d2
Note: 1 is impossible (p-orbitals can hold a maximum of 6 electrons), 4 and 5 are
not ground state configurations, while 3 has 18 electrons.
