He said that matter was made of small, hard particles that he called “atoms”. ]]> 2023-02-10 11:11:49 UTC https://padlet.com/aizabastarrika/omsmw2rrqf1lys24/wish/2476275188 aizabastarrika https://padlet.com/aizabastarrika/omsmw2rrqf1lys24/wish/2476276074 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. ]]> 2023-02-10 11:21:47 UTC https://padlet.com/aizabastarrika/omsmw2rrqf1lys24/wish/2476284489 aizabastarrika https://padlet.com/aizabastarrika/omsmw2rrqf1lys24/wish/2476286869 He improved on Rutherford's model. He proposed that electrons move around the nucleus in certain paths called energy levels.
