Question

When do we call an atom as neutral?

• A. Same number of electron and neutron
• B. Same number of proton and neutron
• C. Same number of proton and electron
• D. None of the choices

Answer 1

The correct option is C

Same number of proton and electron

Neutral atoms will have the same number of protons and electrons and hence the opposite charges carried by these particles cancel each other out making it completely neutral. Eventually, that also indicates that the neutral atom will have the same number of electrons and protons.
