“Atom”From the Greek word atoma, meaning “INDIVISIBLE”.

“Atom”From the Greek word atoma, meaning “indivisible”.Greek Philosopher Democritus could believed that you could only cut matter up a certain amount of times before it was too small to be divided.

Parts of the AtomAll Atoms are mostly EMPTY SPACE surrounding a tiny NUCLEUS.“subatomic particles” – particles that are SMALLER than an atomThere are 3 main subatomic particles.Protons, Neutrons, Electrons
