Electrons are the smallest of the three particles that make up atoms. Electrons are found in shells or orbitals that surround the nucleus of an atom. Protons and neutrons are found in the nucleus. Test out how much you know about atomic structure by taking the quiz below. All the best!

None - they are all very different in size and mass
They all have the same mass
In the atomic nucleus.
outside the nucleus, yet very near it because they are attracted to the protons.
Everywhere, there is no place it cannot be.
Either in the nucleus or around it - electrons are readily found anywhere in an atom
Outside the nucleus and often far from it - most of an atom's volume is its electron cloud.
