Well, darling, francium is a wild child with only one electron in its outermost shell. It's living life on the edge, ready to jump into any chemical reaction that comes its way. Just one electron, but oh boy, does it make a splash!
The largest atom is calcium which has 4 shells.
Rubidium has 5 electron shells. The electron configuration of rubidium is [Kr]5s1.
Francium has one valence electron.
Your question reveals a common confusion between orbitals and shells. Chlorine has three electron shells: the first, second and third. The first shell has just the one orbital, the 1s The second shell has two sub-shells, the 2s and the 2p. There are three p orbitals in the 2p sub-shell. Each orbital can hold two electrons, so there are eight electrons maximum in the second shell. The third shell likewise has two sub-shells, the 3s and the 3p, but the 3p is not completely filled, leaving room for one more electron. When chlorine gains this electron it will become a Cl- ion. This is summed up in the electron configuration 1s22s22p63s23p5.
Francium has 87 protons and 87 electrons.
