Usually with roman numerals, like iron (II) chromate
iron has a charge of 2
or manganese (IV) oxide, manganese has a charge of 4
(these are ionic compounds just to let you know)
On the periodic table, the size of an element's ionic radius follows a predictable trend. The ionic radius increases as you shift down a column or community. This is because every row introduces a new shell of electrons. The ionic radius decreases over a row or time, going from left to right.
The ph of the solution with is 9.0
Ionic bonds are formed due to tendency of a metal to donate an electron and tendency of non metal to gain an electron.
