- Before solving this question, one has to remember the following facts.
- Protons are positively charged particles in an atom.
- Electrons are negatively charged particles in an atom.
- If protons are greater than electrons, then the atom is positively charged.
- If electrons are greater than protons, then the atom is negatively charged.
- If both are equal, then the atom is in neutral state.
- Here, the number of protons = 2
- Number of electrons = 3.
- Since, number of protons < number of electrons
- Therefore, the atom is negatively charged.
Hope you could get an idea from here.
