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

Answer:

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.
