Hi,
The correct answers should be:
Electrons are smaller than protons
The majority of an atom’s mass is in the nucleus
Protons and neutrons are about the same size.
The first option is not true since in the picture you can see three different kinds of particles, while the second one is false since different electrons can occupy different energy levels and the same electron can “jump” from one energy level to another one if stimulated.
Hope this helps! If my answer was not clear enough or you’d like further explanation, please let me know. Also, English is not my first language so I’m sorry for any mistakes.
