A $$d$$ orbital can hold a maximum of how many electrons?

Accepted Answer

$$10$$

Question 14

Which of the following statements about the $$f$$ subshell is TRUE?

Accepted Answer

It is ignored in introductory courses because it has the most shapes.

Question 15

Which of the following best explains why the $$4d$$ sublevel is higher in energy than the $$4p$$ sublevel?

Accepted Answer

The $$d$$ sublevel has more orbitals, increasing electron repulsion.
