which statement correctly compares the valence electrons for atoms of francium (fr) and barium (ba)? (1 point) o barium has more valence electrons, and they are in a higher energy level. o francium has more valence electrons, and they are in a higher energy level. o barium has fewer valence electrons, but they are in a higher energy level. o francium has fewer valence electrons, but they are in a higher energy level.

which statement correctly compares the valence electrons for atoms of francium (fr) and barium (ba)? (1 point) o barium has more valence electrons, and they are in a higher energy level. o francium has more valence electrons, and they are in a higher energy level. o barium has fewer valence electrons, but they are in a higher energy level. o francium has fewer valence electrons, but they are in a higher energy level.

Answer

Brief Explanations:

Francium (Fr) is in Group 1 of the periodic - table and has 1 valence electron. Barium (Ba) is in Group 2 and has 2 valence electrons. Also, as you move down the periodic table, the energy level of the valence electrons increases. Francium is below Barium in the periodic table, so its valence electrons are in a higher energy level.

Answer:

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