B. Inspect the table of polyatomic ions and determine what happens to the charge on the polyatomic ion, phosphate when an H+ is added to the formula? What is the new name?
The formula of hydrogen sulfate, or bisulfate, is written by placing a hydrogen in front of the polyatomic ion formula for phosphate (PO4) –HPO4, and the charge is decreased from 3- to 2-
C. The metals in group 3A, 4A and 5A are not transition metals, however all but 1 has variable charges. What element in Group 3A, period 3 has a fixed charge, and what is that charge
Aluminum. Al,+3
