Question

How are the electron levels and rows of the periodic table related?​

Answer 1

The number of valence electrons in an atom is reflected by its position in the periodic table of the elements.

Step-by-step explanation:

Across each row, or period, of the periodic table, the number of valence electrons in groups 1 2 and 13 18 increases by one from one element to the next.

Answer 2

The highest energy level number (1 through 7) for the electrons in an atom corresponds to the period (or row) in the periodic table to which that atom belongs. Because there are 7 periods in the table, there are 7 energy levels. For example, hydrogen (H) is in the first period, so it has only one energy level.
