Electrons are small negatively charged particles that are found in the electron cloud of an atom. These electrons repel other negatively charged particles and are attracted to positively charged particles. They are important because they play a major role in creating chemical bonds between atoms and contribute to its mass. A scientist by the name of Robert Andrews Millikan won a Nobel Prize for his study and finding of the charge of an electron. His findings greatly helped the scientific community by contributing to the Atomic Theory of Matter, which states that all matter is made out of atoms. Millikan found the charge of an electron by performing an experiment, which we now call Millikan’s Oil Drop Experiment. The Oil Drop Experiment was

Even though it is positive it falls toward the positive plate because gravity is larger than the electric force that keeps it attracted to the negative plate (DeWitt). Millikan then decides to raise the voltage to its highest and notices that the droplet goes toward the negative plate (DeWitt). This happens because the electric charge is a lot larger than the gravitational pull (DeWitt). He then experiments different voltages and notices that having the electric force equals the gravity force the drop stays still. With that they perform several test writing down the mass of drop and the voltage at which it is balanced at (DeWitt). They take the mass of the drops and equal it to the voltage of the plates times the unknown data, which is the charge of the drop (DeWitt). They then find the charge of drops and realize that they are positively charged, each is a multiple of 160, and lose electrons the larger they are. This helps them figure out that the electrons have a charge of -1.6x10-19 coulombs …show more content…
All atoms in one element have the same property and varies in mass (Leon). Combining two or more different atoms form to make compounds and the chemical reaction that takes place rearranges the atoms (Leon). Robert Millikan helped this theory by contributing in the charge and mass of the electron which was then used in many ways. One being that is was implemented into Niels Bohr’s equation for the hydrogen spectrum, thus allowing him to finally calculate Rydeberg’s constant, which describes “the wavelengths or frequencies of light in various series of related spectral lights” (Britannica and AIP). Since it helped Niels Bohr’s solve Rydeberg’s constant, it in turn help give the first more important proof to the new Atomic Theory of Matter (Chemistry
