When an atom looses electrons, it becomes a positive ion. Hence, option (a) is correct.
The atoms are the smallest unit of matter which consist of centrally located hard mass, known as nucleus. The nucleus is made of positively charged particles, known as protons and neutral particles, known as neutrons. On the other hand, electrons tend to revolve around the nucleus.
- The electrons are the negative charged sub-particles, that tends to revolve around the nucleus in specific energy levels.
- The protons are found inside the Nucleus, therefore a complete atomic structure consists of electrons and protons as sub-atomic particles.
Each atoms tends to have same number of electrons and protons. As per the given problem, if an atom loses an electron, then the number of protons will exceed the electrons and net charge on atom will be positive. Hence, atoms will get converted into a positive ion.
Thus, we can conclude that when atoms looses electrons, it becomes a positive ion. Hence, option (a) is correct.
