The answer you're looking for is
It is formed when an atom loses electrons.
Explanation ??
Well, the electrons are the negative part of an atom right? And protons are the positive part of the atom! We learned that when all of us were younger and first learning about atoms. The main reason it isn't "It is formed when an atom gains protons" is because most atoms have protons, it can still be negative as long as it has more electrons than protons. So that leaves us with, "It is formed when an atom loses electrons." I believe this is correct because since it is losing electrons, it is losing the negativity!
(( Max ))
A positively charged ion is formed during reactions when an atom loses
electrons.
During chemical reactions, electrons are lost and gained as elements strive
to obtain a stable octet configuration. This is done through series of bonding techniques and processes such as covalent bond etc.
When an atom loses electrons it becomes a positively charged ion and
when an atom gains an electron it becomes negatively charged.
