Atomic Structure Question 200

Question: The total spin and magnetic moment for the atom with atomic number 7 are:

Options:

A) ±3,,3BM

B) ±1,,8BM

C) ±32,,15BM

D) 0,8BM

Show Answer

Answer:

Correct Answer: C

Solution:

  • Atomic number = 7 Structure is 1s2,2s2,2p3

[1],[1],[1] n=3 Total spin = ±12n=±12×3=±32 Magnetic moment = n(n+2)

=3(3+2)=15 BM
