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

Francium has more valence electrons, and they are in a higher energy level.
Francium has more valence electrons, and they are in a higher energy level.

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

Barium has more valence electrons, and they are in a higher energy level.

Answer 1

To compare the valence electrons of francium (Fr) and barium (Ba):

• Francium is in Group 1 of the periodic table and has 1 valence electron.
• Barium is in Group 2 of the periodic table and has 2 valence electrons.

Francium is also in Period 7, while barium is in Period 6, meaning that the valence electrons of francium are in a higher energy level compared to those of barium.

Based on this information, the correct statement is:

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