Answer 1

The option that correctly describes the pattern of valence electrons on the periodic table is:

The number of valence electrons increases from left to right.

As you move from left to right across a period, the number of valence electrons in the elements increases. For example, the alkali metals on the far left have one valence electron, while the noble gases on the far right have eight valence electrons (except helium, which has two).
