Ba has no charge overall but the Barium ion has a 2+ charge.
Barium's charge is 2+ and Chlorine's charge is 1- so the formula would be BaCl2
Barium form cations with the charge +2.
Barium forms a +2 charge, along with all other group 2 metals.
BaSO4 is barium as well as a sulfate anion. The overall charge of BaSO4 includes a +2 charge for barium, and a -2 charge for the sulfate anion.
+2
2+
It's ionic because barium has a 2+ charge while the hydroxide has a 1- charge.
BARIUM
Barium's atomic number is 56. Thus, barium has 56 positively charged protons in its nucleus. To have a net charge of 0, then, barium must also have 56 electrons.
No, positive 2. :)
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
