https://padlet.com/anegoitisolo/703ob3barfta3axm Everything is made of atoms. They are really small (tiny) particles. They are so small that we cannot see them with our eyes. Atoms are made of three particles: protons, neutrons and electrons. en-us 2023-02-08 11:18:26 UTC 2023-02-15 11:17:00 UTC hello@padlet.com https://padlet.net/icons/png/269b.png anegoitisolo https://padlet.com/anegoitisolo/703ob3barfta3axm/wish/2474753948 He proposed that matter could not be divided into smaller pieces forever. He said that matter was made of small, hard particles that he called “atoms”.

All substances are made of atoms. Atoms are small particles that cannot be created, divided, or destroyed. Atoms are invisible.
Atoms join together to make new substances (molecules).

He discovered the protons and nucleus.
