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.
Three. In fact, any element in the same column of the periodic table as nitrogen will also gain three electrons when forming an ion.
1 electron
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-.
Selenium will gain two electrons and arsenic will gain three electrons
0 he has glasses
In phosphene it gain 4 electrons. Phosphate lose 4 electrons
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.
None.Calcium loses 2 electrons to form an ion.
Selenium can gain 1 electron or loss 2, 4, 6 electrons.
Three. In fact, any element in the same column of the periodic table as nitrogen will also gain three electrons when forming an ion.
