Answer 2

Answer:

Principal Quantum Number

Explanation:

The main energy level quantum number, n, is the Principal quantum number. The rows of a periodic table correspond to the principal quantum numbers. You start at the lowest main energy level and work your way up. Counting numbers is as simple as 1, 2, 3, 4, and so on. When you reach n = 7, you will have completed the current periodic table. So you don't have to count all the way to the end.
