Key concepts
3 concepts
- 1
Atoms are the basic units of matter and are composed of even smaller subatomic particles called protons, neutrons, and electrons.
- 2
The nucleus of an atom contains protons and neutrons, while electrons are found in the electron cloud, which makes up most of the atom's volume.
- 3
Protons have a positive charge, electrons have a negative charge, and neutrons have no charge, meaning they are neutral.
