Question

Select the single best answer. Select the statement which explains the meaning of the symbol 3d^5. The principal quantum number (n) is 2, the angular momentum quantum number I) is 4, and there are 4 electrons in the subshell. The principal quantum number (n) is 2, the angular momentum quantum number (I) is 5, and there are 5 electrons in the subshell. The principal quantum number (n) is 3, the angular momentum quantum number () is 2, and there are 5 electrons in the subshell. The principal quantum number (n) is 3, the angular momentum quantum number (I) is 5, and there are 2 electrons in the subshell.

Explanation / Answer

n = 3 since it show which level we are, therefore ignore A and B

the angular momentum is "d"

s, p, d = 0, 1, 2, then L = 2

ignore D since l is not 5; anyways

d^5 , the 5 show the number of electrons in such subshell

choose C
