Barium (Ba) will typically have a +2 charge as it is a group 2A element.
The name for this ion is:barium ion
Ba2+ is the ion of the Ba atom. That means it has given away two electrons to other atoms in order to reach a stable state with 8 electrons in its outer shell.
Barium forms a +2 charge, along with all other group 2 metals.
The valency of a barium ion is +2. Barium chloride (BaCl2) consists of a barium ion (Ba^2+) and two chloride ions (Cl^-), which gives the overall compound a neutral charge.
A Ba atom forms a +2 ion because it loses two electrons from its outer shell to achieve a stable octet configuration, similar to the nearest noble gas configuration of xenon. This results in a Ba^2+ ion with a filled outer shell, making it more stable than the neutral atom.
Barium ion = Ba2+ Hydroxide ion = OH- The compound they make is Barium hydroxide = Ba(OH)2which is a precipitate insoluble in water.

Barium forms a +2 charge, along with all other group 2 metals.
A cation is a positively charged ion. Barium ion is Ba^2+, chloride ion is Cl^-, nitrate ion is NO3^-, and chromate ion is CrO4^2-.

A Ba atom forms a +2 ion because it loses two electrons from its outer shell to achieve a stable octet configuration, similar to the nearest noble gas configuration of xenon. This results in a Ba^2+ ion with a filled outer shell, making it more stable than the neutral atom.
When a barium atom forms its most common ion, it loses two electrons to achieve a stable octet configuration, resulting in a 2+ ion with a charge of +2.
When Ba(OH)2 dissociates in water, it forms Ba2+ ions and 2 OH- ions. The Ba2+ ion carries a double positive charge and is a cation, while the OH- ions are hydroxide ions and carry a single negative charge as anions.
Barium sulfate (BaSO4) is a neutral compound with no overall charge. In this ionic compound, the barium (Ba) ion has a +2 charge, and the sulfate (SO4) ion has a -2 charge, which balance each other out to give a net charge of zero for the compound.
The cation of barium is Ba(2+).
Ba has no charge overall but the Barium ion has a 2+ charge.
