Inside an Atom
Open to everyone until Thursday, October 1
To keep it, print it while it is open.
An atom has a tiny, dense center called the nucleus. Around it, even smaller electrons move, held by the electric pull from the center.
In the picture
- Red sphere in the central cluster: a proton, which carries a positive electric charge.
- Gray sphere in the central cluster: a neutron, which has no electric charge.
- Central cluster: the nucleus, the dense core of the atom.
- Blue sphere on a looping path: an electron, which carries a negative electric charge and is held by electric attraction.
Examples
- The helium inside a party balloon is made of helium atoms.
- A copper wire contains many copper atoms, each with a nucleus and electrons.
Key takeaways
- Atoms are mostly empty space around a very small, dense nucleus.
- Protons are positive, electrons are negative, and their electric attraction keeps electrons around the nucleus.
