Both iodine and chlorine are halogens (group 17) and have 7 valence electrons.
11 electrons makes the third energy level complete. One

How many Chlorine (Cl) atoms there are. Since Cu has a valence shell of 2, it needs to bond with 2 Chlorine ions in order to create complete valence shells for the molecule.
There are 7 valence electrons in a chlorine atom. The atomic number of chlorine is 17, which means it has an electron configuration of 2,8,7. This shows it has 3 shells of electrons, with 7 in the outer level.
The element chlorine has seven electrons in its valence shell.
One chlorine atom will form an ionic bond with one magnesium atom. The magnesium will donate its two valence electrons to the chlorine atom, filling both of their valence electron shells.
Chlorine has 7 valence electrons.
Radium has seven electron shells; the valence of radium is 2+.
In every chlorine atom, there are seven valence electrons.
I think that because chlorine has 17 electrons in all, and ten of them are filled up on the first two shells, then seven of them should be on the third shell, so seven of them are valance electrons.
There are 7 electrons on the valence shell. Chlorine requires one electron to make it complete and the ion would therefore be Cl- (one minus charge)
