A) 6 electrons
B) 2 electrons
C) 4 electrons
D) none of these
Correct Answer: B
Solution :
Each electron in an orbit of an atom is designated by a set of four quantum numbers. Principle quantum number (n): It tells the energy level in which the electron lie and the size of the atom, various shell are denoted by K, L, M, N.... etc., (1, 2, 3. 4.... shell). Angular momentum quantum number or azimuthal quantum number (l): It has value from 0 to n -1. The sub-shells are designated as s, p, d f...........Value of \[l\] | Sub ? shell |
0 | S |
1 | P |
2 | D |
3 | F |
4 | G |
5?. | h?. |
