How many electron shells woul be completely filled by a neutral xenon atom?

Answer 1

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.

Answer 2

Three energy shells would be filled. This is true because there are 17 electrons in the element chlorine and it would take three shells to contain all 17 electrons.

Answer 3

Chlorine has 7 electrons in the outer shell. It requires one electron to fill the outer shell.

Answer 4

cholrine has 17 electrons, therefore it has 7 on its outershell. it would need one more electron to bond i.e Na 1 and CL7 = Na+CL-

Answer 5

a neutral chlorine atom has 17 electrons; 2 in the K shell, 8 in L and 7 in M. Only K and L are completely filled, so the answer is 2.

Answer 6

Xenon has five electron shells.
