Chlorine will gain one electron when forming an ion. Chlorine therefore fills its valence electron shell with 8 e-. Chlorine usually bonds with group 1 metals, like Na (Sodium).
Chlorine gain an electron in chemical reactions.
Selenium may lose 2, 4 or 6 electrons and may gain 2 electrons.
1 electron
Chlorine has 7 valence electrons.
It will lose 2 to form Sr2+
A chlorine atom will gain one electron when forming an ion. That will give the ion a charge of 1-.
Cl has a tendency to gin electrons in a reaction, this is due to the fact that it has 7 electrons already, its much easier for chlorine to gain one more electron to have a full shell than to lose 7 and have a full shell.
Chlorine gain an electron in chemical reactions.
Selenium may lose 2, 4 or 6 electrons and may gain 2 electrons.
One, and only one.
1 electron
Chlorine needs to gain one electron to have a full outer shell and achieve a stable electron configuration.
A chlorine atom must gain one electron to complete its octet, as it has 7 electrons in its outer shell and needs 8 to achieve a stable electron configuration.
In a chemical reaction, chlorine will typically gain one electron to have the full octet. This is referred to as the octet rule. Since chlorine has seven valence electrons because it is in row 7A, it gains one so it can have 8 electrons.
Chlorine has seven valence electrons. It shows a higher tendency to gain electrons because of its relatively high electronegativity, and therefore directly combines with many other elements.
Krypton can gain a maximum of 2 electrons to achieve a stable octet configuration, forming the Kryptonide anion. It does not typically lose electrons.
Just one. To become stable, it needs eight electrons; a full outer shell.
