Quote:…the statistics and spins of the lighter elements can only be given a consistent description if we assume the neutron is an elementary particle.

The discovery of Polonium (named after Poland) which is 300 times more radioactive than uranium and the discovery of Radium which is several million times more radioactive than uranium / Created the word Radioactivity – which is produced by radioactive elements / They give off heat without a chemical reaction taking place

Fontaine Chu, Krystal Xie and Ryan Yu POINTS

was an American physicist

he was able to measure the charge on the electron

Quote: Be less curious about people and more curious about ideas

Parker POINTS

Misinterpreting results lead to not discovering the neutron / Starting a new investigation by bombarding aluminum with helium alpha particles converted stable aluminum atoms into radioactive atoms – artificially creating radioactive atoms / Also produced radioactive nitrogen from boron and radioactive silicon from magnesium

Quote: For my part, I consider science to be the paramount interest of my life.

Parker POINTS

Investigating the deflection of alpha particles by atoms lead to rethinking the nature of the atom / Large-angle deflections could not be explained by the old model / The change in the path of some alpha particles is due to a small, densely packed centre of positive charge called the nucleus.

Measuring the charge of an electron by spraying oil drops in a chamber and exposing them to X rays, thereby making them positively or negatively charged. Negatively charged oil drops were moved upward by adjusting the electric charge and knowing the weight of the drop, the mass of the electron was discovered.
