The atom is composed of subatomic particles: protons, neutrons, and electrons that affect the properties
of an atom.
● Protons and neutrons have about the same mass.
● Protons have a positive charge, while neutrons have no charge.
● Electrons have a negative charge.
● Protons and neutrons are tightly bound in a tiny nucleus.
● The nucleus is located in the center of the atom with the electrons moving in random patterns in the
space around the nucleus.
Students use the information found on element squares to create atomic models
