Question

Which statement correctly compares the valence electrons for atoms of francium (Fr) and barium (Ba)?

Answer 1

Answer:

Francium has fewer valence electrons, but they are in a higher energy level

Answer 2

From the Periodic Table...

Francium is a group 1 Element and Barium is a Group 2 Element

This statement is a giveaway as it already tells you that Barium has more valence electrons than Francium since it has 2 electrons in its Outer shell.

This Eliminates Options A and B

Francium has more electrons than Barium

So It should be at a higher energy level.
