Web5 apr. 2024 · Now here our element is Hydrogen (H) which lies in group 1 of the periodic table. Hence the ionic charge of Hydrogen (H) is 1+. Note: The blank area shown in the above periodic table are mostly the transition … Web20 apr. 2024 · In a hydroxide (OH −) ion, we see that the total charge of the ion is −1. That means, the total sum of the oxidation numbers of the elements present in the ion totals out to be −1. The ion has one oxygen atom and one hydrogen atom. Hydrogen is less electronegative than oxygen, and so will possess its usual +1 state. flat round makeup sponge
