Question

which is formed by lose of one or more electron by an atom​

Answer 1

Explanation:

When an atom gains or loses an electron, it attains a net charge and becomes an ion. When electrons are lost (or donated), the resulting ion is called cation. When electrons are gained, the resulting ion is called an anion. Thus, cations have a net positive charge, while anions have a net negative charge.
