Chlorine typically gains one electron to form a stable chloride ion. This process involves the attraction of one electron.
A chlorine atom typically has 17 electrons in its electron cloud.
A charged chlorine atom, or a chlorine ion, would have gained or lost an electron. If it gained an electron, it would have a charge of -1. If it lost an electron, it would have a charge of +1.
This is a chemical element. You can find the how many electron in a single atom by using a periodic table.
17 protons and 17 electrons in chlorine.
7
Sodium has one outer ring electron, and chlorine has seven outer ring electrons. Sodium tends to lose its outer electron, while chlorine tends to gain an extra electron to achieve a stable electron configuration.
Only one, from sodium to chlorine.
The electron configuration of chlorine is 1s2 2s2 2p6 3s2 3p5. Each separated letter in that notation represents a distinct electron orbital. Therefore, there are 5 electron orbitals in chlorine.
-1
Chlorine can donate one electron to achieve a stable electron configuration. It tends to form anions by gaining one electron to reach a full outer shell.
None - the electron goes from sodium TO the chlorine.
