Since it has 1 more electron than protons, chlorine has a charge of –1, making it a negative ion. When ions form, atoms gain or lose electrons until their outer energy level is full. For example, when ...

The attraction by chlorine is stronger than the attraction by sodium. An electron is transferred from sodium to chlorine. Sodium becomes a positive ion and chlorine becomes a negative ion. The ...

Removing Chlorine, Fluorine: Uncharged Organic Molecule Can Bind Negatively Charged Ions Date: February 28, 2008 Source: Indiana University Summary: ...

Chlorine will gain an electron and form a negative ion. The ionic bond is the force of attraction between the oppositely charged ions - a positively charged metal ion and a negatively charged non ...

So although chlorine has a mass number of 35 which means it has 18 neutrons, ... The ion has two positive protons but three electrons so it is a negative ion. 1 of 2. Previous image Next image.

So, sodium atom will donate one electron to chlorine atom and forms a sodium ion i.e. Na+. On the other side chlorine atomic number is 17 , its electronic configuration is 2,8,7 .
