Unit 3 Chemistry Test

What is the maximum number of electrons that any one orbital can hold?

According to the Pauli Exclusion Principle, an orbital can hold a maximum of 2 electrons.

What is the total number of electrons that can theoretically be placed in the seventh energy level?

The number of electrons that can be put in the 7th orbital is 98. 2n^2 is the formula, and you plug in 7 for n.
