Answer 1

The correct option is:

The number of valence electrons increases from left to right.

In the periodic table, as you move from left to right across a period, the number of valence electrons in the outer shell of the atoms increases. For example, elements in Group 1 have one valence electron, while elements in Group 18 (noble gases) have eight valence electrons.
