Chlorine has 7 valence electrons.
Chlorine-35 has three full shells of electrons. It has two electrons in the first energy level, eight electrons in the second energy level, and seven electrons in the third energy level, making a total of 17 electrons.
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.
Two electrons in the first level, 8 in the second, 7 in the third. The electron configuration notation is: 1s22s22p63s23p5, or [Ne]3s23p5. Incidentally, this is the same arrangement as in chlorine-37, which is chlorine's only other isotope.
The noble gas distribution for chlorine (Cl) is 2,8,7. This means it has two electrons in the first energy level, eight electrons in the second energy level, and seven electrons in the third energy level. Chlorine achieves stability by gaining one electron to complete its outer energy level to achieve the same electron configuration as argon, a noble gas.
