Guida verificata passo dopo passo1
Recall the basic properties of subatomic particles: protons, neutrons, and electrons.
Understand that protons have a positive charge, neutrons have no charge (neutral), and electrons have a negative charge.
Recognize that protons and neutrons are located in the nucleus of an atom, while electrons are found in the electron cloud surrounding the nucleus.
Compare the masses: protons and neutrons have similar masses, which are much greater than the mass of electrons.
Use these facts to evaluate each statement and identify the one that correctly describes how electrons differ from protons and neutrons.
