Which option correctly describes the pattern of valence electrons on the periodic table?(1 point)

Question

The number of valence electrons increases from bottom to top.
The number of valence electrons increases from right to left.
The number of valence electrons increases from top to bottom.
The number of valence electrons increases from left to right.

Answer 1

The correct option is: The number of valence electrons increases from left to right.

On the periodic table, as you move from left to right across a period, the number of valence electrons in the elements increases. For example, elements in Group 1 (alkali metals) have 1 valence electron, while elements in Group 2 (alkaline earth metals) have 2, and so on, until the noble gases in Group 18, which have 8 valence electrons (except for helium, which has 2).
