The electronic configuration of chlorine is 2,8,7
So there are 7 electrons in the valence shell (or highest energy level).

The chloride ion (Cl-) has 8 electrons on the outermost energy level.
well, on the periodic table of elements a chlorine atom has 17 electrons, usually the first level holds up to two electrons and the second level holds up to 8. so if my figuring is correct there should be fifteen electrons on the second energy level.
2. the number of electrons on the outermost level is always equal to the group number. Barium is group 2 therefore it's outermost energy level contains 2 electrons
The 3rd energy level is the highest occupied energy level for chlorine with seven electrons.
There are 3 energy levels in chlorine. Look at the shell notation: 2-8-7. So there are 8 electrons in the highest energy level.

7 electrons
Chlorine has 7 valence electrons.
The electronic arrangement of chlorine is 2, 8, 7. This means that chlorine has 2 electrons in its first energy level, 8 electrons in its second energy level, and 7 electrons in its outermost energy level.
Chlorine is in the 17th period.Elements in the 17th period have 7 electrons in the outermost energy level. So chlorine has 7 electrons in the 3rd energy level.Chlorine has 17 electrons. It's electron configuration is [Ne] 3s2 3p5. Therefore it has 7 electrons in its third (outermost) energy level.
Sr has two electrons in the highest occupied energy level
There are 7 electrons in a chlorine atom's highest energy level, as is true for all elements in column 17 of a wide form periodic table, if the relatively slight differences between 3s and 3d electrons and between paired and unpaired 3d electrons are ignored. If these smaller differences are taken into account, there is only one electron on chlorine's last energy level: the only unpaired 3d electron.
No, the farthest electrons are at the highest energy level.No, the farthest electrons are at the highest energy level.No, the farthest electrons are at the highest energy level.No, the farthest electrons are at the highest energy level.
The highest energy level is called the "electronegativity".
