The statement that is not true about subatomic particles is Proton and neutrons have the same charge.

The other statements are true about sub-atomic particles;

Protons and neutrons have almost the same mass.
Protons and electrons have opposite charges.
Unlike protons and electrons, neutrons have no charge.

Further Explanation

An atom

An atom is defined as the smallest particle of an element that can take part in a chemical reaction.
Atoms are made of energy shells and the inner nucleus.

Subatomic particles

Protons

Protons are subatomic particles that are found in the nucleus of an atom. They are positively charged. with a charge of +1.
The number of protons differ from one element to another and thus used as the atomic number of an individual element.
The nucleus of an atom is positively charged due to the positive charge of the protons.
Additionally, protons do not take part in chemical reactions but in nuclear reactions.

Neutrons

They are sub-atomic particles in an atom that are found in the nucleus of an atom. They have a zero charge or no charge.
Neutrons are slightly heavier than protons.
The number of protons and neutrons in a nucleus of an atom results to the atomic mass number of an atom. Like protons they only take part in nuclear reactions.

Electrons

They are found orbiting the nucleus on energy shells based on Clouds’ theory. Electrons are negatively charged each with a charge of -1.
The number of electrons and protons in a neutral atom are equal. Additionally they have the least mass of the three sub-atomic particles.
Electrons are the only sub-atomic particles that take part in chemical reactions.
