Question

why cannot hydrogen ion exist alone​

Answer 1

Heya mate...

well that's very easy...

hydrogen is a gas... which generally is found in diatomic state...

its stable form is diatomic... coz it has only one e in its outermost shell... hence needs only one to pair...

hence it cant exist alone.

hope it helps ✌

Answer 2

hydrogen ions r positively charged,so it will try to attract negativly charge particles ND to repel with positively charged particle to became neutral

so it is unstable in ionic form
