Barium forms a +2 charge, along with all other group 2 metals.
The name for this ion is:barium ion
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.
Barium has two electrons in its outermost shell, electrons carrying a negative charge. When the Barium atom becomes an ion, these two electrons are lost. Now the Barium atom has more protons than electrons, meaning a net positive charge of 2.
Ba has no charge overall but the Barium ion has a 2+ charge.

A barium ion has a charge of 2+ and an iodide ion has a charge of 1-, therefore, two iodide ions are needed to balance the barium ion. Ba2+ + 2I- --> BaI2
2+
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.
The barium ion has a charge of +2. It loses two electrons to become positively charged.
Barium ion = Ba2+ Hydroxide ion = OH- The compound they make is Barium hydroxide = Ba(OH)2which is a precipitate insoluble in water.
The negative ion for barium sulfate is sulfate (SO4) with a charge of 2-.
Barium has two electrons in its outermost shell, electrons carrying a negative charge. When the Barium atom becomes an ion, these two electrons are lost. Now the Barium atom has more protons than electrons, meaning a net positive charge of 2.
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-.
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 chemical formula for a compound with one barium ion and two chloride ions is BaCl2. The barium ion has a 2+ charge, while the chloride ions each have a 1- charge, so it takes two chloride ions to balance the charge of one barium ion.
