A chlorine atom will gain one electron when forming an ion. That will give the ion a charge of 1-.
A chlorine atom would gain one electron to become an ion because it tends to achieve a stable electron configuration by having a full outer shell of electrons.
7 electrons in its outer shell, although it can also lose or gain electrons in chemical reactions.
Molecules that have a high tendency to gain or lose electrons are most likely to become ions. Common examples include metals, such as sodium and potassium, which tend to lose electrons to form positive ions, and nonmetals, such as chlorine and oxygen, which tend to gain electrons to form negative ions.
Chlorine will gain electrons in the reaction with calcium. Chlorine is a halogen, which tends to gain an electron to achieve a full outer shell, while calcium is a metal that tends to lose electrons to achieve a stable electron configuration.
Bromine tends to gain one electron to become a Br- ion.
A chlorine atom would gain one electron to become an ion because it tends to achieve a stable electron configuration by having a full outer shell of electrons.
negatively
As fluorine is a halogen (the group in which the elements are more reactive as they are one electron lesser than that of the octet configuration)and hence it can only gain electrons.
lose 2
gain or lose electrons
negatively
It needs to lose, or gain, electrons.
to become stable
7 electrons in its outer shell, although it can also lose or gain electrons in chemical reactions.
bcc it's the same
