Ba2+
The chemical formula for barium perxenate is Ba2O8Xe. It is composed of one barium ion (Ba2+) and one perxenate ion (XeO4^2-).
The chemical formula for barium ions is Ba2+ and for iodide ions is I-.
The chemical formula of barium chloride is BaCl2.
The chemical formula BaBrO2 corresponds to barium bromite. It is a compound made up of one barium ion (Ba2+) and a bromite ion (BrO2-).
I believe that would be Barium nitrate or Ba(NO3)2
BaI2 is the chemical formula for Barium Iodide.
The chemical formula for barium nitride is Ba3N2. This compound is formed by the combination of the barium ion (Ba2+) and the nitride ion (N3-). The subscripts in the formula are determined by the charges of the ions to ensure overall charge neutrality.
Barium ion = Ba2+ Hydroxide ion = OH-
The chemical formula for Barium Carbonate is BaCO3
The chemical formula of barium nitrate is Ba(NO3)2. It is composed of one barium ion (Ba2+) and two nitrate ions (NO3-).
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.
The chemical formula for barium periodate is Ba(IO4)2. It is composed of one barium ion (Ba2+) and two periodate ions (IO4-).
