Question

Select the statement which explains the meaning of the symbol 6d5.


A. The principal quantum number (n) is 6, the angular momentum quantum number (ell) is 5, and there are 2 electrons in the subshell.

B. The principal quantum number (n) is 6, the angular momentum quantum number (ell) is 2, and there are 5 electrons in the subshell.

C. The principal quantum number (n) is 5, the angular momentum quantum number (ell) is 5, and there are 5 electrons in the subshell.

D. The principal quantum number (n) is 5, the angular momentum quantum number (ell) is 4, and there are 4 electrons in the subshell.

Answer 1

Answer:

B. The principal quantum number (n) is 6, the angular momentum quantum number (ell) is 2, and there are 5 electrons in the subshell.

Explanation:

Given;

electronic configuration of 6d⁵

where;

6 in the configuration shows that, the principal quantum number (n) is 6

d is the subshell

d orbital has angular momentum quantum number (l) of 2

            s orbital, l = 0

            p orbital, l = 1

            d orbital, l = 2

            f orbital,  l = 3

5 in the configuration means that there are 5 electrons in the subshell

Therefore, 6d⁵ symbol means that "The principal quantum number (n) is 6, the angular momentum quantum number (ell) is 2, and there are 5 electrons in the subshell".
