_______ made the first synthetic pigment (paint).
_______ Discovered isomerism (This is when the same number of atoms of the same elements combine in different ways to make different compounds. This shows that the arrangement of atoms in compounds is important).
_______ Discovered that diamonds were made of carbon.
_______ Came up with the idea that links (bonds) between atoms could explain how atoms formed compounds.
_______ Also came up with the idea of chemical bonds. Although he came up with the idea after the other scientist, he published the idea first and received the credit for the idea.
_______ Solved the problem of engines from knocking by adding lead to them. Unknown to him, this will cause many other problems.
_______ Discovered radioactivity when he observed that UV light made uranium crystals glow.
_______ Studied radioactivity and discovered the elements polonium and radium.
_______ Discovered the nucleus of the atom and came to the conclusion that the number of protons in the nucleus could change through the process of alpha decay.
_______ Discovered the neutron.
_______ Claimed to have made elements heavier than uranium.
_______ Disproves the above scientist’s claim of making elements heavier than uranium.
_______ Explains Fermi’s work and recognizes that the uranium atom had split in two (nuclear fission).
_______ American research project lead by Oppenheimer and made up of many scientists whose goal was to make an atomic bomb.
_______ Created the first synthetic element. It is not found in nature and is heavier than uranium. They named it neptunium.
