Two different sub-atomic particles are described below:

Question

Particle X: No charge
Particle Y: Outside the nucleus

Which statement is true? (5 points)

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.

Answer 1

The correct answer is:

a
X is a neutron and Y is an electron.

Explanation:

• Particle X is described as having "no charge," which corresponds to a neutron. Neutrons are found in the nucleus of an atom and have no electrical charge.
• Particle Y is described as being "outside the nucleus," which corresponds to an electron. Electrons are negatively charged particles that orbit the nucleus of an atom.
