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

(1 point)

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

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

  4. I don't think it's c. Look at these on the periodic table. Ba is 56 and Fr is 87. Fr has 1 valence electron; Ba has two. Fr is in period 7 while Ba is in period 6. So that single electron in Fr is in a higher energy level than the two in Ba.

  5. I think it’s ‘Francium has fewer valance electrons, but they are in a higher energy level’
    Since they are on a higher period but has one less valence electron than Barium.
