chlorine has 7 valence electrons.
There are 7 outer orbital electrons in an atom of chlorine, as it has 7 electrons in its outermost energy level.
ionic bond
Oxygen has 2 electrons in the innermost orbital and 6 in the outermost (valence) orbital.
One atom of sodium has one electron in its outermost orbital.
C = 1s2,2s2,2p2 so the outermost (2p) orbital has 2 electrons in Ground State
Two. The valence shell is six and the 6s orbital has 2 electrons.
6. Electronic configuration, 1s2 2s2 2p6, 3s2, 3p5
There are 8 electrons in the outermost energy level of a chlorine ion in table salt. Chlorine typically has 7 electrons in its outer shell, but when it becomes an ion in table salt, it gains an extra electron to achieve a full outer shell of 8 electrons.
The chloride ion (Cl-) has 8 electrons on the outermost energy level.
7 electrons in 3s and 3p (outermost) orbitals
helium has 2 valence electrons (in s orbital) and has complete s orbital. So it does not need to gain or lose more electrons to be stable.
There are 17 paired electrons in a chlorine atom because it has 17 protons and 17 electrons, with each electron occupying a specific energy level and orbital.
