He said that matter was made of small, hard particles that he called “atoms”. ]]> 2023-02-10 11:10:53 UTC https://padlet.com/olaialuzarraga/dy00jjwa32pplc9i/wish/2476274310 olaialuzarraga https://padlet.com/olaialuzarraga/dy00jjwa32pplc9i/wish/2476275113 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).]]> 2023-02-10 11:11:44 UTC https://padlet.com/olaialuzarraga/dy00jjwa32pplc9i/wish/2476275113 olaialuzarraga https://padlet.com/olaialuzarraga/dy00jjwa32pplc9i/wish/2476279908 He proposed that in the center of the atom is positively charged part called the nucleus. He discovered the protons and nucleus.

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