Write the values of all the four quantum numers for the last electron of k
Answers
All the four quantum numbers are :-
1 principal quantum number
2 Angular momentum quantum number
3 Magnetic quantum number
4 Spin quantum number
The values of all four quantum numbers for the last K electrons are 4,0,0,+1/2 or -1/2
Answer:
4,0,0,±½
Explanation:
The four quantum numbers for an atom refer to the state of the valence or outermost electron.
The four numbers are:
n is the distance of the electron from the nucleus, and can be 1,2,3,4etc,
l is the shape of the orbital of the electron, from 0 to n−1
Ml is the orientation of the orbital, ranging from −l to +l, and
Ms is the spin property of the electron, either + ½ or −½
For a potassium atom, the electron configuration is 1s²2s²2p^64s¹, which means that n=4.
It also means that, since the outermost electron is in an s orbital,
l=0.
Ml can range from −l to +l, but if l=0 because it is an s orbital, then Ml must be 0, too.
Ms can be either + ½ or - ½, depending on the spin of the electron, it doesn't particularly matter in this case.
Therefore, the full set of quantum numbers for a K atom is 4 ,0,0,±½
