Within an atom, electrons
are outside the nucleus and are motionless.
are in motion outside the nucleus.
are inside the nucleus and are motionless.
are in motion inside the nucleus.

The correct answer is B. Are in motion outside the nucleus

Explanation:

An atom (unit of matter) includes protons, electrons, and neutrons. Besides this, in atoms protons and neutrons are located in the nucleus or center, while electrons orbit this nucleus in orbits according to different electron shells. Besides this, electrons differ from other sub-particles because they are negatively charged which causes electrons to influence properties such as electricity or magnetism. According to this, it can be concluded electrons are outside the nucleus and these are in motion.
