Here is answers to question of [[CP Questions on Brief History of Atom Table - Revised 2022-2023]]. These questions including Rutherford but excluding Bohr and Schrodinger.<br> <br> 1) Plum Pudding Model<br> <br> 2) Rutherford<br> <br> 3) electrons<br> <br> 4) compounds are made up of 2 or more elements in a fixed mass ratio.<br> <br> 5) Dalton<br> <br> 6) Electrons<br> <br> 7) protons and neutrons<br> <br> 8a) Atoms are indivisible (can not divide it). Atoms are made of subatomic particles (protons, electrons, neutrons). But it is still the smallest particle though, that also retains its characteristics)<br> <br> 8b) Atoms of the same element are the same including mass. Isotopes are by definition, atoms of the same element that differ by mass (actually # of neutrons)<br> <br> 9a) Atoms combined in a simple fixed number ratio (that also mean fixed mass ratio) to form compounds.<br> <br> 9b) Different atoms of different elements are different including mass. For our chemistry world, that is correct (real answer is that in a nuclear reaction an element can become another different element (but it is predetermined you do not have a chose).<br> <br>
