A physicist who determined the chare of an electron by means of his oil-drop experiment?
There are two scientist working together: The oil drop experiment was an experiment performed by Robert Millikan and Harvey Fletcher in 1909 to measure the charge of the electron (the elementary electric charge).
Which scientist furthered knowledge of the electron by determining its charge and mass using an oil-drop experiment in 1909?
Robert Millikan
Robert millikan's major contributions to the atomic theory?
Millikan: He discovered that the weight of an electron is 1840 times smaller than a hydrogen atom (atomis mass of 1) Thomson: Thomson was the first person to suggest the theory of the atom containing positive and negative particles, and demonstrated the latter which called electrons
What are the uses of oil drop experiment of robert millikan at present?
In this method oil droplets in the form of mist was produced by an atomiser and they were allowed to enter through a tiny hole in the upper plate of electrical condenser.The downward motion of these droplets was viewed through a telescope wid micrometer eye peice. By measuring the rate of fall of these droplets, Millikan was able to measure the mass of oil droplets. Also the air inside the chamber was ionized by passing Xray beams thru it.The electrical charge on these droplets was acquired by collision with gaseous ions...For more information...check in yahoo answers
Why was Millikan's discovery important?
Millikan performed the oil drop experiment where he sprayed a very fine mist of oil and manipulated the falling rate of the oil using x-rays. By doing this, he could measure the electron's charge, a particle previously discovered in the cathode ray tube experiment which effectively determined the mass to charge ratio. Millikan calculated the charge of an electron to be -1.602x10-19 columbs. Therefore, the mass must be 9.109x1031 kg. Since the electron was found to have a negative charge, the implication existed that there must be a positive charge located somewhere in the atom since atoms are naturally neutrally charged.

What was Millikan able to determine about electrons through a series of experiments?
Millikan discovered that electrons had a negative charge using his Oil Drop experiment.
Who performed the oil drop experiement?
Robert Millikan in 1909
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.

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.
