Ba^(2+)
Lithium form the cation Li2+.
In the periodic table, Ba is in the 2nd group, making it have a charge of 2 and it is a metal so it's a cation, making it lose electrons(+) so its charge would be Ba2+. (2+ is a superscript)
Ag+ cation
Barium (Ba) will typically have a +2 charge as it is a group 2A element.
Ba^(2+)
The cation of barium is Ba(2+).

Barium (Ba) will typically have a +2 charge as it is a group 2A element.
Cs+ cation
Ag+ cation
No. helium does not form cation
Yes - Al -----> Al3+ is the cation.
Potassium will most likely form a cation with a +1 charge.
Rubidium will form cation: Rb+
When it looses two electrons, it'll become a Mg2+ cation
