What is the Ionic Charge of Hydrogen (H)? And Why?

Charge of Hydrogen (H)

The Ionic Charge of Hydrogen (H) is 1+.

But the question is how can you find the ionic charge on Hydrogen (H)?

Well there are 2 methods by which you can find the ionic charge of Hydrogen (H).

Lets dive right into these methods one by one.

If you are a visual learner like me, then here is a short two minute video for you.

Method 1: By looking at the ionic charge trends on periodic table

This is a very simple method to determine the ionic charge of the monatomic ions.

First of all, let’s look at the group-wise ionic charge trends on the periodic table.

ionic charge trends on periodic table

You can see in the above periodic table that; 

  • Elements of group 1 have 1+ ionic charge,
  • Elements of group 2 have 2+ ionic charge,

(Exclude transition metals, because they have variable ionic charges)

  • Elements of group 13 have 3+ ionic charge,

(Exclude group 14, because they can have 4+ or 4- ionic charges)

  • Elements of group 15 have 3- ionic charge,
  • Elements of group 16 have 2- ionic charge,
  • Elements of group 17 have 1- ionic charge,
  • Elements of group 18 have 0 ionic charge,

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 and post-transition elements.
They show variable ionic charge.
Hence we cannot find their ionic charge by simply looking at the periodic table.
In order to find the charge of these elements, we need to look at what it is bonded with.
For more information, read the example of finding the charge of Copper.

Okay so now let’s see another method to find the ionic charge of Hydrogen (H).

Method 2: By using electron configuration

The electron configuration of Hydrogen is: 1s1. [1]

You can see that the outermost orbit of Hydrogen has 1 electron.

During the chemical reaction, hydrogen loses this 1 electron.

And as the Hydrogen (H) loses 1 electron, it forms H+ ion. 

Hence the ionic charge of Hydrogen (H) is 1+.

I hope you have understood the reason behind the 1+ charge of hydrogen.
