What is Millikan atomic theory?

What is Millikan atomic theory?

During the 1890s the theory that electricity was conveyed by a miniscule unit, the electron, gained acceptance. By measuring how the various drops of oil moved about, Robert Millikan showed that their charge always was a multiple of a precisely determined charge – the electron’s charge.

What did Millikan discover about atoms?

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.

What did Robert Millikan’s oil drop experiment prove?

Explanation: Millikan’s oil drop experiment proved that electric charge is quantized. This was the big result of the oil drop experiment. That he could also determine the charge of the electron was a secondary benefit.

What did Millikan’s experiment lead to?

Explanation: Millikan’s oil drop experiment proved that electric charge is quantized. At the time, there was still great debate whether electric charge was continuous or not. Millikan believed that there was a smallest unit of charge, and he set out to prove it.
