What was Robert Millikan theory?

Work. During the 1890s the theory that electricity was conveyed by a miniscule unit, the electron, gained acceptance. In 1910 Robert Millikan succeeded in precisely determining the magnitude of the electron’s charge.

What did Robert Millikan discover about the electron?

Millikan discovered that there is a fundamental electric charge—the charge of an electron. Rutherford’s gold foil experiment showed that atoms have a small, dense, positively charged nucleus; the positively charged particles within the nucleus are called protons.

Why was Robert Millikan’s discovery important?

Robert Millikan’s accomplishments were the design and fine-tuning of experiments which unambiguously confirmed the most important scientific theories of his time, providing the implications for atomic theory. His oil drop experiment confirmed the existence of the electron and accurately determined its charge.

What did the scientist Millikan discover?

March 22, 1868 – December 19, 1953 Robert Millikan was a physicist who discovered the elementary charge of an electron using the oil-drop experiment.

What was Millikan’s conclusion?

Millikan, carrying out a long and tedious task that involved a set of collateral experiments, repeated the experiment numerous times, eventually concluding that the results obtained could be explained if there was a single, elementary charge (the value of which he determined) and the charges identified were integer …

What experiment did Millikan do and what did he discover?

Robert Millikan’s oil-drop experiment. By comparing applied electric force with changes in the motion of the oil drops, he was able to determine the electric charge on each drop. He found that all of the drops had charges that were simple multiples of a single number, the fundamental charge of the electron.

What conclusion did Millikan make?

What did Millikan conclude about his experiment?

What did Millikan’s experiment prove?

What did Millikan’s oil-drop experiment reveal? It determined the charge of a single electron to be -1.6 ⋅ 10 ^-19 and also showed that all charges were multiples of the fundamental electron charge.

How did Robert Millikan change the atomic model?

Robert Millikan was able to determine the mass of an electron by using charged oil drops. Electrons have such a small mass, they were believed to be massless. Millikan’s experiment determined that the electrons did, indeed, have mass.

What is the conclusion of Millikan oil drop experiment?

Milliken’s Oil Drop Experiment Conclusion The charge over any oil droplet is always an integral value of e (1.6 x 10-19). Hence, the conclusion of Millikens Oil Drop Experiment is that the charge is said to be quantized, i.e. the charge on any particle will always be an integral multiple of e.
