Basically, what Millikan did was suspend tiny charged droplets of oil between electrically charged plates. This allowed him to calculate the amount of charge on the oil droplet, by determining the electrical force require to just cancel out the effect of gravity on the droplet. What he found was that each droplet had a charge which was a small integer multiple of a constant, which he interpreted as the charge on a single electron. His value was within about 1% of the commonly accepted value today determined using much more sophisticated equipment.

What is the significance of Millikan's oil drop experiment?
Millikan found the charge of an electron- or pretty close to the accepted value
Who measured the charge on the electron?
Sir Joseph Thomson (J.J. Thomson) determined the charge of the electron in 1897, calling them "corpuscles." Previously electron beams had been referred to as Lenard rays and cathode rays.J.J. Thompson with his cathod ray tube experiment.
How does an electron become charged?
It doesn't really "become" charged. An electron is always charged, and it can only have a charge of -e where value of elementary charge e is 1.602 * 10-19 C as found first by Millikan with his famous oil drop experiment
Which oil was used in oil drop experiment?
clock oil
What was The oil drop experiment hypothesis?
yes it is

When did Robert Millikan contribute to atomic theory?
Robert A. Millikan conducted many experiments throughout his long, distinguished career. If you're referring to the famous "oil drop" experiment that measured the quantum of electric charge, Millikan and Harvey Fletcher performed that particular one in 1909.
Millikan's oil drop experiment helped determine the mass of an electron by allowing scientists to measure which of these?
the charge carried by an electron A+
Which scientist furthered knowledge of the electron by determining its charge and mass using an oil-drop experiment in 1909?
Robert Millikan
Who calculated the negative charge of an electron?
The brilliant, so-called "Oil-drop experiment" of Robert A. Millikan established the magnitude of the quantum of electric charge ... the amount of charge on each electron (negative) and each proton (positive). Search around on line for "Millikan oil drop experiment" to read the fascinating story of how it was done.
