Answer 1

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

• Barium (Ba) is in Group 2 of the periodic table, which means it has 2 valence electrons.
• Francium (Fr) is in Group 1 and has 1 valence electron.

Now, considering their energy levels:

• Barium is in the 6th period, while francium is in the 7th period. Francium has a higher energy level because it is in a higher period.

Based on this information, the correct statement is: Francium has fewer valence electrons, but they are in a higher energy level.
