[From: ] [author: ] [Date: 12-04-30] [Hit: ]
2, - 2,(c) ( 3, 0, 0,(d) Two of these are correct.......
(a) ( 3, 1, 0, + ½ )
(b) ( 3, 2, - 2, - ½ )
(c) ( 3, 0, 0, + ½ )
(d) Two of these are correct.
(e) None of the above

and why?

15P: 1s2 2s2 2p6 3s2 3p3 (15 electron are distributed)

3p3 means:
3º shell, than... the first quantum number is 3

the subshell is "p"
"s" is 0 for the subshell, "p" has 1 to the number of subshell.

the 3º number:

The subshell is formed for 3 orbitals.... Px Py and Pz. The last electron was putted in the Pz. The 3 number of P orbitals are, respectivelly, -1, 0, +1. Pz is the +1 orbital.

The last quantum number...
It talk about the spin of electron, +1/2 or -1/2

Answer:
e) 3, 1, +1, 1/2 or -1/2
