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

(1 point)
Responses

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

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.

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

To compare the valence electrons of francium (Fr) and barium (Ba), we first need to identify their positions in the periodic table.

  • Barium (Ba) is located in Group 2 and has 2 valence electrons.
  • Francium (Fr) is located in Group 1 and has 1 valence electron.

Both elements are in the same period (Period 6 for Francium and Period 5 for Barium), indicating that Francium's electrons are in a higher energy level compared to Barium's.

Given this information, the correct statement from your choices would be:

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