| Baekeland | created a polymer plastic, made famous called "Bakelite" |
| Smalley | discovered carbon chains that are fullerenes, known as buckyballs and nanotubes |
| Rutherford | found that radioactive atoms will decay into different particles like alpha, beta, and gamma |
| Currie | found radioactive polonium and radium, died from radioactive overexposure |
| Bakewell | found that certain minerals natural release radioactive rays like x-rays, alpha and beta particles |
| Lewis | found that valence electrons will exchange atoms when elements bond together |
| Rutherford | found the positive charge of the atom was located in the atoms nucleus |
| Kirchhoff & Bunsen | found that burning substances give a spectrum of light, which is unique for different substances |
| Thomson | extracted a piece of the atom that had a negative charge called the electron |
| Davy | founded electrochemistry, reacting substances by passing electricity through them |
| Wohler | found that organic and inorganic substances have the same basics, wich are elements |
| Mendeleev | orgainized elements by properties, trands, periods, and groups into what is called the Periodic Table of Elements |
| Kekule | found that elements can combine into compounds of links called rings (benzene ring) |
| Avogrado | Gases are made by multiple parts and form new compounds called molecules. |
| Dalton | Elements have relative weights that can be measured, called Atomic Mass |
| Priestley | Tested air by capturing oxygen from plants into beakers, then burning powders to see the effects. |
