5. e I’m an electron! I’m a proton! I’m a neutron! P N

6. e I was walking along and I saw these two. I was telling jokes to the neutron. The proton and I were having fun. P N

7. e They looked so happy there together. I was p o s i t i v e l y charged! I couldn’t have amassed more happiness. P N P N P N P N e e e

8. e The proton looked happy, so I wandered closer. I could see the electron coming near. The who? Huh? e e e e e e e e e e e e e e e e e e e e e e e e e e e e e e e P N

9. They were HUGE next to me! The electron was so cute! Like a speck of dust, or something… e P N

10. I didn’t want to seem obvious, so I kept walking. Around and around the electron goes. Hey electron, you’re making the proton dizzy. e e e e e e e e e e e e e e e e e e e e e e e e P N

11. The proton seems so happy with the neutron. I’m having fun, but I still notice the electron. It won’t bother me if the electron hangs around. e P N P N P N P N P N P N P N

12. I guess I’ll just wander around out here. I’m happy hanging out here. The center is cool, but sometimes it can be a “Bohr”. e e e e e e e e e e e e e e e e e e e e P N

13. Electrons circle around the nucleus of an atom. Protons are a main part of the nucleus of an atom. Neutrons also hang out in the nucleus of an atom. e e e e e e e e e e e e e e e e e e e e e e e e e e e e e e e e P N

14. Electrons have a negative charge.  Protons have a positive charge. + Neutrons have no charge. 0 e e e e e e e e e e e e e e e e e e e e e e e e e e e e e e e e P N

15. Electrons are little and have a mass of almost zero. Protons are big and have a mass of one. Neutrons are also big and have a mass of one. e e e e e e e e e e e e e e e e e e e e e e e e e e e e e e e e P N
