Question

I want to know ${H^ + }$ and ${H^ - }$ ion ground state configuration?

Answer 1

A hydrogen ion is formed when a hydrogen atom gains or loses an electron. A hydrogen ion which contains a positive charge formed when an electron is removed from a hydrogen atom; hence it is the nucleus of hydrogen. Similarly hydrogen ions which contain negative charge formed when an electron is gained by the hydrogen atom.

Complete answer:
A hydrogen atom is made of one proton and one electron. So, after losing the electron it has only protons. Thus, represent as ${H^ + }$. It is also referred to as proton $^1{H^ + }$ , i.e. the Cation of protium. As we know it contains only protons so its charge is $+ 1$. The electronic configuration of ${H^ + }$ in ground state is:
${H^ + } = \;1{s^0}$
As, there is only one electron in the hydrogen atom and thus, after losing it; it has zero electron.
Hydrogen anion, ${H^ - }$ is the negative ion of the hydrogen atom. It indicates the extra electron present in the shell. It is also known as hydride. Because of containing extra electrons it is also known as protide, $^1{H^ - }$. As we know it contains extra electrons so its charge will be $- 1$. The electronic configuration of hydrogen anion in the ground state is:
${H^ - } = \;1{s^2}$

Note:
Hydrogen cation is used to make the ATP synthase in Photosynthesis. As enforced through the membrane, the lower concentration occurs in the cytoplasm whereas higher in the thylakoid membrane. On the other hand, in the process of Osmosis, the Hydrogen cation is forced out of the membrane through ATP synthase.
