Where did Robert A Millikan do his work?
Robert A. Millikan conducted his famous oil drop experiment at the University of Chicago in the early 20th century. This experiment allowed him to accurately measure the charge of an electron for the first time.
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
Who was the first scientist to measure speed and distance over time?
Galileo Galilei was one of the first scientists to measure speed and distance over time. He used inclined planes and rolling balls to investigate acceleration and the law of falling bodies.
What E-word was the first elementary particle to be discovered?
The electron was the first elementary particle to be discovered in 1897 by J.J. Thomson. It is a fundamental constituent of matter and carries a negative electric charge.
Who invented ammeter first?
The ammeter was first invented by German scientist Johann Christian Poggendorff in 1820. He developed the device to measure electric current flowing through a conductor.
What experiment did Millikan do?
Robert Millikan was the first to measure the electrical charge of an electron.
What was Robert Millikan?
Robert Millikan was the first Physicist to measure the electrical charge of the electron.
The scientist who first proposed the order of electron distribution within orbitals was who?
Friedrich Hermann Hund
Why there is big gap between first and second ionization energies?
Ionization energies are the amount of energy needed to remove an electron from an atom in the gaseous state, thereby giving the atom a positive charge and making it an ion. Ions get a +1 charge for each electron lost. It is this positive charge of the atom that makes the second ionization energy considerably greater than the first. Not only does the second electron have to overcome the initial attractive forces to nucleus, it must also overcome the extra +1 charge the atom has after the loss of the first electron, which simply takes more energy.
Who determined the charge on a single electron?
the charge of either a single proton, or the absolute charge of a single electron is approximately 1.602176487(40)×10−19 coulombs .The magnitude of the elementary charge was first measured in Robert A. Millikan's noted oil drop experiment in 1909
How did Millikans experiment change your view on atoms?
Millikan measured the first the electrical charge of an electron.
Robert A. Millikans contributions to the atomic theory?
Robert A. Millikan was the first to determine the electrical charge of the electron.
Where did Robert A Millikan do his work?
Robert A. Millikan conducted his famous oil drop experiment at the University of Chicago in the early 20th century. This experiment allowed him to accurately measure the charge of an electron for the first time.
In the first group of elements in the periodic table what does the first group have in common?
They all have one valence electron in their outer shells and so tend to lose that electron in chemical reactions, gaining a +1 charge.
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
What is formed when the first ionization energy is applied to an aton?
A positive ion with a single charge and a "free" electron are formed.
Which scientists experiments revealed the charge of an electron in a atom?
Altering or varying the gas in the cathode ray tube had no effect on the cathode ray it produced, therefore it was concluded that the negative particles of the rays were found in all types of matter.
