Protons- a stable subatomic particle occurring in all atomic nuclei, with a positive electric charge equal in magnitude to that of an electron, but of opposite sign.

Neutrons- a subatomic particle of about the same mass as a proton but without an electric charge, present in all atomic nuclei except those of ordinary hydrogen.]]> 2017-10-26 21:12:19 UTC https://padlet.com/507649/t0f1zejmdko4/wish/201033611 j.j Thompson 507649 https://padlet.com/507649/t0f1zejmdko4/wish/201035726 found negativity charged participial called electrons ]]> 2017-10-26 21:22:49 UTC https://padlet.com/507649/t0f1zejmdko4/wish/201035726 james chadwick 507649 https://padlet.com/507649/t0f1zejmdko4/wish/201035784 mass balance- discovered the neutron ]]> 2017-10-26 21:23:14 UTC https://padlet.com/507649/t0f1zejmdko4/wish/201035784 Dalton 507649 https://padlet.com/507649/t0f1zejmdko4/wish/201035923 atoms are particles - undividable - specific ratio ]]> 2017-10-26 21:24:00 UTC https://padlet.com/507649/t0f1zejmdko4/wish/201035923 Rutherford 507649 https://padlet.com/507649/t0f1zejmdko4/wish/201035960 Gold foil experiment - atoms are mostly empty space - nucleus has a positive charge & all the mass ]]> 2017-10-26 21:24:10 UTC https://padlet.com/507649/t0f1zejmdko4/wish/201035960 Millikan 507649 https://padlet.com/507649/t0f1zejmdko4/wish/201035997 oil drop test- mass of electrons ]]> 2017-10-26 21:24:19 UTC https://padlet.com/507649/t0f1zejmdko4/wish/201035997 Bohr 507649 https://padlet.com/507649/t0f1zejmdko4/wish/201036194 discovered electrons travel in orbitals or energy levels ]]> 2017-10-26 21:25:20 UTC https://padlet.com/507649/t0f1zejmdko4/wish/201036194
