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.
Chlorine has three electron shells with 2, 8, 7 electrons.
The electron configuration of chlorine is 1s2 2s2 2p6 3s2 3p5. Each separated letter in that notation represents a distinct electron orbital. Therefore, there are 5 electron orbitals in chlorine.
Plutonium has seven electron shells.
Magnesium has 3 electron shells. The electron configuration is : 2,8,1
Uranium has seven electron shells.
Francium has seven electron shells; electrons per shell: 2, 8, 18, 32, 18, 8, 1.
Chlorine has three electron shells with 2, 8, 7 electrons.
The electron configuration of chlorine is 1s2 2s2 2p6 3s2 3p5. Each separated letter in that notation represents a distinct electron orbital. Therefore, there are 5 electron orbitals in chlorine.

Rubidium has 5 electron shells. The electron configuration of rubidium is [Kr]5s1.
Two energy shells. Made up as 1s2, 2s2 Shells 1 & 2 each have only 's' orbital and each orbital has only two electrons in it. The outer shell '2' is more energetic. The electrons are paired and spin in opposite directions to each other.
Plutonium has seven electron shells.
Chlorine (Cl) has 17 electrons in its shells.
I think you mean electron orbits, shells or clouds. It has three, consisting of 2, 8 and 7 electrons respectively.
chlorine has 7 valence electrons.
Magnesium has 3 electron shells. The electron configuration is : 2,8,1
The correct number of electron clouds or shells sodium has is 3.
