He said that matter was made of small, hard particles that he called “atoms”. ]]> 2023-02-14 11:24:30 UTC https://padlet.com/nahiacarbayeda/69g43e43emcv1on4/wish/2481608197 nahiacarbayeda https://padlet.com/nahiacarbayeda/69g43e43emcv1on4/wish/2483185345 He created the very first atomic theory. 
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.

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