Particles and a Nucleus
Open to everyone until Saturday, October 3
To keep it, print it while it is open.
A hot, crowded cloud contains tiny particles. Protons and neutrons can join into a small central core while electrons move separately.
In the picture
- A lone electron: a tiny negative particle moving by itself.
- A proton: a heavier positive particle.
- A neutron: a heavier particle with no electric charge.
- A compact nucleus: protons and neutrons joined in a tight core.
Examples
- Droplets on a cold window can merge into one larger drop.
- A magnet can pull loose paper clips into a tight cluster while other clips stay apart.
Key takeaways
- Protons and neutrons can join to form atomic nuclei.
- Electrons are much lighter and can stay separate from nuclei.
