Question

the correct set of quantum numbers of unpaired electron of chlorine atom atomic number 17 is EC 1s2 2s2 sp6 3s2 3p5

Answer 1

Hey mate here is your answer ⤵⤵⤵

The atomic number of chlorine is 17. Its electronic configuration is 1s22s22p63s23p5 or [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

3) Magnetic quantum number, (ml) = can be +1, 0 or -1

4) Electron spin quantum number (ms) = 1/2

Answer 2

Answer:

The atomic number of chlorine is 17. Its electronic configuration is 1s^22s^22p^63s2^3p^5 . 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

3) Magnetic quantum number, (ml) = can be +1, 0 or -1

4) Electron spin quantum number (ms) = 1/2
