how many energy levels it has
how many energy levels it has

the ionic charge it forms
the ionic charge it forms

the number of valence electrons it has

Answer 1

The correct response is:

**how many energy levels it has**

The period number in the periodic table indicates the principal energy level (or shell) of the electrons in an atom. For example, elements in period 1 have one energy level, elements in period 2 have two energy levels, and so on.
