What is the sum of principal quantum number(n) and azimuthal quantum number(() of theunpaired electron of chiorine?

Answer»

The atomic number of chlorine is 17. Its electronic configuration is 1s22s22p63s23p5or [Ar]3s23p5. It contains a single unpaired electron in the 3p orbital. Thus, the electron in the 3p orbital will have the following set of four quantum numbers

1) principal quantum number, n = 3

2) Azimuthal quantum number, l = 1

therfore the number of unpaired electrons of chlorine=4
