The most fundamental building blocks of all matter are atoms. There are a variety of different types, and they come in a wide range of sizes. What makes them interesting is that they contain electrons – which can be either negatively or positively charged. The balance between the two charges determines whether an atom will react with other atoms, thus creating molecules and compounds.
Ever wonder what atoms are made of?
- Atoms are made of protons, neutrons, and electrons.
- Protons have a positive charge and electrons have a negative charge.
- Neutrons don’t have any charge but they can change their form to become either a proton or an electron.
