Two different sub-atomic particles are described below:

Particle X: No charge

Particle Y: Outside the nucleus

Which Statement is true?

A. X is a neutron and Y is an electron.

B. X is a neutron and Y is a proton.

C. X is a proton and Y is an electron.

D. X is an electron and Y is a proton.

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

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.
