What happens if you add an electron to chlorine gas?

Adding an electron to a chlorine atom to form a chloride ion produces a negatively charged ion, which increases the overall negative charge of the chlorine gas. This creates a more stable arrangement due to the full valence electron shell, resulting in a more reactive species.

A chlorina atom becomes a chloride in when this happens?

A chlorine atom becomes a chloride ion when it gains one electron to achieve a full outer shell of electrons, becoming negatively charged. This process typically occurs when the chlorine atom interacts with a metal atom in a chemical reaction.


What happens when chlorine gains an extra electron?

When chlorine gains an extra electron, it becomes a negatively charged ion known as chloride (Cl-). This makes the atom more stable and allows it to participate in ionic bonding with other elements.


When sodium and chlorine combine what happens to the electrons?

When sodium and chlorine combine to form sodium chloride (table salt), sodium donates an electron to chlorine. Sodium becomes a positively charged ion (Na+) while chlorine becomes a negatively charged ion (Cl-). This ionic bond forms due to the attraction between the oppositely charged ions.
