https://padlet.com/arettehernandez/z9sc5n8kuvxclv5f Everything is made of ATOMS. They are really small particles .They are so small that we cannot see them with our eyes. en-us 2023-02-10 11:07:43 UTC 2023-02-14 09:59:22 UTC hello@padlet.com https://padlet.net/icons/png/269b.png arettehernandez https://padlet.com/arettehernandez/z9sc5n8kuvxclv5f/wish/2476275061 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).]]> 2023-02-10 11:12:10 UTC https://padlet.com/arettehernandez/z9sc5n8kuvxclv5f/wish/2476275520 arettehernandez https://padlet.com/arettehernandez/z9sc5n8kuvxclv5f/wish/2476276799 He discovered negatively charged particles inside the atom (electrons).

He discovered the protons and nucleus.

He proposed that electrons move around the nucleus in certain paths called energy levels.
