They are so small that we cannot see them with our eyes. en-us 2023-02-14 08:29:06 UTC 2023-02-15 11:27:24 UTC hello@padlet.com https://padlet.net/icons/png/1f9ea.png unaxzabaleta1 https://padlet.com/unaxzabaleta1/1tlex5pao5gmh7m1/wish/2481124606 He had an idea of an atom, meaning a piece of matter that was not able to be divided]]> 2023-02-14 08:31:49 UTC https://padlet.com/unaxzabaleta1/1tlex5pao5gmh7m1/wish/2481124606 unaxzabaleta1 https://padlet.com/unaxzabaleta1/1tlex5pao5gmh7m1/wish/2481127495 He created the very first atomic theory. All substances are made of atoms.
