We also acknowledge previous National Science Foundation support under grant numbers 1246120, 1525057, and 1413739. Solution Because the ionic compound must be electrically neutral, it must have the same number of positive and negative charges. Moving from the far right to the left on the periodic table, elements often form anions with a negative charge equal to the number of groups moved left from the noble gases. By this means, a positively charged ion is formed. For compounds in which the ratio of ions is not as obvious, the subscripts in the formula can be obtained by crossing charges: use the absolute value of the charge on one ion as the subscript for the other ion.
