Answer:

This question is incomplete

There are three main subatomic particles namely electrons, protons and neutrons. However, the question only discusses two of them; electrons (negatively charged) and protons (positively charged).

A. Found in all matter

Answer: They are <u>both</u> found in all matter since all matter are made up of atoms and all atoms have both protons and electrons (and even neutrons).

B. Negative charge

Answer: The subatomic particle with negative charge (as discovered by R.A Millikan) is the <u>electron</u>

C. Exists in the nucleus

The subatomic particles found in the nucleus are the <u>protons</u> and neutrons.

D. Attract opposite charges

They <u>both</u> (protons and electrons) attract opposite charges because they are of opposite charges and generally unlike charges attract.

E. Moves at extreme speed

Of the two subatomic particles mentioned, <u>electrons</u> move faster than protons because of there lighter mass when compared to the protons. However, the fastest subatomic particle is the neutrino.

F. Bound by strong force
