A scientist who made an expirament that was better then rutherfords expirament his was more avanced becuase with milikan's expirament you could study one drop at a time but rutherfords expirament requird you to study the whole cloud and by stuying the drop you could figure more out about the substance.

Who conducted experiments to determine the quantity of charge carried by electron?
With his oil drop experiment, R.A. Milikan attempted to learn about the quantity of change carried by an electron. His discoveries are instrumental to particle and atomic theories.
Who performed the oil drop experiement?
Robert Millikan in 1909
Who are some famous chemists and what are their contributions?
Below is a list of world-famous chemists:Alfred Nobel (1833-1896), Swedish chemist, engineer, best known for isolating dynamiteLuis Federico Leloir (1906-1987), Argentine biochemist and winner of the 1970 Nobel Prize for research into sugar nucleotides, metabolism of carbohydrates, and renal hypertensionTeunis Ven-der Linden (1884-1965), Dutch chemist, developed insecticide "Lindane"Jabir bin Hayyan (721-815), A Persian polymath and considered the father of modern chemistry. He invented of over twenty types of now-basic chemical laboratory equipment, such as the alembic and retort. He discovered sulfuric acid, and by distilling it together with various salts, Jabir discovered hydrochloric acid (from salt) and nitric acid (from saltpeter).Democritus (460-370B.C.), Greek philosopher introduced idea that matter consisted of atoms having physical size and shape which constantly moved in a void and interacted in different waysDaniel Rutherford (1749-1819), discovered nitrogenRobert Boyle (1627-1691), English physicist and chemist. Experimented in pneumatics (the study of mechanical properties of air and other gases). Through research he rejected the accepted definition of matter and Proposed Boyle's Law (1662)Henry Canvendish (1731-1810), English physicist and chemist, discovered hydrogen (1766), and discovered nitric acidJohn Dalton (1766-1844), English chemist and physicist,(1793), developed atomic theory. His theory (1805) accounts for the law of conservation of mass, law of definite proportions, and law of multiple proportions, he also reduced the first table of atomic weightsAmedeo Avogadro (1776-1856) stated that equal volumes of gases, at the same temperature and pressure, had the same amount of molecules, proposed the Avogadro's Law which states that, "Equal volumes of gases contain the equal number of molecules when the given temperature and pressure are same for all the gases." The number of molecules present is known as, Avogadro's number and is 6.023 x 1023Joseph Louis Gay-Lussac (1778-1850), French chemist and physicist, developed the law of volumes concerning the combination of gases, and also discovered BoronRobert Wilhelm Bunsen (1811-1899), German chemist, helped develop the spectroscope, introduced the Bunsen burner that was actually developed by his laboratory assistant, Peter Desaga, discovered elements Cesium and RubidiumDmitri Ivanovich Mendeleev (1834-1907), Russian chemist, Developed the periodic table by placing the elements in order of increasing atomic weight (1869), Predicted the existence and properties of elements that would fill the gaps left in his chart (1871), These elements were discovered between 1875 and 1885Joseph John Thomson(1856-1940) English physicist, Researched atomic structure, Discovered that atoms contained particles which he called "electrons" by testing the ratio of cathode ray particles to their mass and found out that they were always equal. he Received Nobel Prize for physics (1907) and developed the mass spectrograph with Francis William Ason (1919)Robert Andrews Milikan(1868-1953)American physicist, Succeeded in measuring, quite accurately, the minimum electric charge that could be carried by a particle (1911)Ernest Rutherford(1871-1937) British physicist from New Zealand, Discovered several radioactive isotopes with colleagues (1899-1905), Classified forms of radiation as alpha, beta, and gamma; received Nobel Prize for chemistry (1908)Svante Arrhenius (1859 -1927) - He proposed the equation now known as the Arrhenius equation. He was also one of the first chemists who proposed that when in a solution the salt dissociates into ions even in the absence of an electric current.Jons Jacob Berzelius (1779 - 1848) - Swedish, gave the technique of chemical formula notations. He also proposed the law of constant proportions, which proved that inorganic substances are made of elements that are in constant proportion by weight.Marie Curie (1867 - 1934) - Polish born chemist and physicist, discovered the radioactive elements radium and polonium for which she was awarded the Nobel Prize in Chemistry.Michael Faraday (1791 - 1867) - discovered the aromatic compound benzene.
Who measured the charged of an electron?
Robert Milikan
Did Robert milikan work with anyone?
yes no maybe so
Who was the trumpet section for a chorus line 1985 movie?
I know that Bob Milikan played lead.
What did Robert milikan contribute in science?
he discovered the the electron has a negative charge through an experiment called the oil-drop experiment
Which school is better CAMS Milikan Poly or Cabrillo?
CAMS! (California Academy of Mathematics and Science) is way better although there's a lengthy application process. But it's worth it! CAMS is in the top 5o schools nationwide. Poly, Milikan, and Cabrillo didn't even make the list. I'll be going to CAMS for 2009-2013!
What was Robert Millikan's discovery and when did it happen?
In 1908 Milikan discovered the charge of the elctron which is 1.60 x 10-19. He also confirmed Albert Einstein's theory of the photoelectric effect. He won the noble peace prize in physics, for his discovery of the electron's charge, in 1923.
Why did the magnets cancel deflection in the experiment for discovering electrons?
"Discover electrons"!!! You mean the Leonhard experiment that sent a ray of electrons through a cathode ray tube and observed the change in the spot of light at the screen? But there WAS no "cancelation", so I'm not sure what you're asking. But there was another experiment that needs to be considered part of the "discovery" of the electron: that of Milikan: the oil-drop experiment. Between the work of Leonhaard (which established the ratio of the electronic mass to the electronic charge) and that of Milikan (which established the charge of the electron) the experimental foundations of the discovery were provided. It ws docuemtned by J. J. Thompson (in "The Electon, early 20th centry") Walter Ludwig Schubert, historyofmatter@hotmail.com

What did Robert milikan discover?
Millikan's oil-drop experiment demonstrated that charge is quantized, and that the quantum of charge ... the 'elementary' charge ... is 1.6 x 10-19 Coulomb.
In Milikan's experiment an oil drop of radius 1.64 m and density 0.851 gcm3 is suspended in a chamber when a downward-pointing electric field 1.92105 NC applied Find charge on drop in terms e?
q = mg/E Once you get q divide it by e (1.6E-19) to get your answer. And remember, it will be negative Explanation: http://dev.physicslab.org/Document.aspx?doctype=3&filename=AtomicNuclear_MillikanOilDrop.xml

What do you consider as the greatest Physics invention among all the one's mentioned in the Physics TimeLineWhy do you think so?
The Milikan Oil drop experiment. Its simplicity. Its importance in establishing experimentally once and for all, that particles (electrons) exist. Their charge/mass ratio, e/m, was determined by this experiment very very accurately. It established one of the critical first fundamental constants necessary for opening up the fundamental nature of matter at the quantum level. Even though quantum mechanics was a couple decades away, this experiment opened the door for experimental physics at the quantum level.
