    The answer is: A. X is a neutron and Y is an electron.

    Explanation:

    The sub-atomic particles inside an atom are:

    Neutron: A particle with no charge. inside the nucleus of the atom. Proton: A particle with positive charge, inside the nucleus of the atom. Electron: A particle with negative charge, moving around the nucleus of the atom.

    Since the particle X in the problem has no charge, this particle is a Neutron. And, as the particle Y is outside the nucleus, it has to be an electron. So the right answer is A.

    A neutron has no charge (neutron_>neutral) and is inside the nucleus, an e - has a - charge and is outside the nucleus. A proton has a pos cbarge abd is inside tge nucleus.

    So A must be the answer
