https://padlet.com/hodeimerchan/736ovmohrgho8uml Everything is mode of atom. They are really small (tiny) particles. They are so small that we cannot see wit hour eyes. Atoms are made up of three particles; protons, neutrons and electron. en-us 2023-02-09 11:04:31 UTC 2023-02-15 08:45:35 UTC hello@padlet.com https://padlet.net/icons/png/1f52c.png hodeimerchan https://padlet.com/hodeimerchan/736ovmohrgho8uml/wish/2474851729 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.
