Barium forms a +2 charge, along with all other group 2 metals.
Iodide is monovalent anion. It is I+The charge of the iodide ion is 1-
No. The acetate ion has a -1 charge.
Sodium ions have a charge of 1+

Most likely, hydrogen will form a cation, meaning it will have a positive charge of +1

Calcium forms a 2+ ion.
KCl's Charge is neutral since K has a charge of 1+ and Cl has a charge of 1-
Barium forms a +2 charge, along with all other group 2 metals.
No. Magnesium forms an ion with a 2+ charge while fluorine forms an ion with a 1- charge, so the resulting compound is MgF2. MgF3 would require magnesium to have a 3+ charge, which would be unstable.

potassium
Bromine forms anion. It gets a charge of -1 to form bromide ion.
