Question

How does an element's period number relate to the number of the energy level of its
valence electrons?​

Answer 1

Energy level of its valence electrons? PERIOD NUMBER = ENERGY LEVEL OF VALENCE ELECTRONS

Answer 2

Explanation:

Ques:-How is the energy level of an atom's valence electrons related

Answer => ... For NON-transition metals, the energy level n is given by its period number, i.e. its row number. Being on the fourth row of the periodic table means your valence electrons would be the 4s and 4p electrons, n=4 .
