Do attractive forces have less hold on electrons farther from the nucleus?
Yes, as electrons get farther from the atomic nucleus they are less attracted to that nucleus, which is exactly what you would expect on the basis of Coulomb's Law, F=q1q2/r2 as the radius of the orbit increases the attractive force becomes decreased.
What did Wilhelm Roentgen contribute in the history of atom?
William Roentgen discovered x rays and Roentgen rays. Charles Darwin's contribution was the theory of evolution. John Dalton's contribution was the atomic theory.
Elements are organized in the periodic table by their?
The periodic table is a function of the atomic number.
What determines the amount of energy an electrons has?
distance from the atomic nuclei
What metal is the lightest titanium gold silver aluminum?
aluminum is the lightest atomic #13 titanium atomic #22 silver atomic #47 gold is heaviest atomic #79
How does 1 Coulomb be equal to six point three to the power of eighteen?
1 Coulomb is NOT equal to (6.3)18. It is, in fact 6.24 * 1018 atomic unit (r elementary charge).
What is the relationship between electrostatics and the structure of the atom?
Atomic structure is predominantly determined by the Coulomb force. The Coulomb force, i.e. force between charges is inversely proportional to distance, is the force of electrostatics. The Coulomb force is the force of attraction between the nucleus and the electrons and it is the force of repulsion between the electrons. Quantum mechanics is the theory which uses this force law in determining electronic structure of atoms and molecules. If one wants to get picky and look for very small influences on atomic structure that are not due to the Coulomb force, then one has to investigate the subject of special relativity and some very weak nuclear interactions.
What did Millikan Contributed at the atomic structure?
Robert A. Millikan was an American experimental physicist. He measured the charge on the electron. (minus 1.602 176 53(14) x 10−19 coulomb)
Did the first atomic bomb dropping or Charles Lindbergh's famous flight occur first?
Charles Lindbergh's flight across the Atlantic ocean occured in 1927; the first atomic bomb dropped in 1945. Therefore, Charles Lindbergh's famous flight occured first.
Who was the pilot on bockscar during the atomic bombing?
Major Charles W. Sweeney
Who were the pilots that dropped the atomic bombs on Hiroshima and Nagasaki?
charles sweeney and paul tibbets
Who dropped the second atomic bomb on nagasaki?
The aircraft, named Bock's Car, was commanded by Major Charles Sweeney.
What type of electrical charge to protons have?
Positive charge (equivalent to 1.602176565(35)×10−19 coulombs).
What has the author Charles Spencer Pitcher written?
There is no known author named Charles Spencer Pitcher in literary or historical records.
Did Charles Lindburgh's famous flight or the dropping of the first atomic bomb or the Civil Rights enactment occur first?
The first Civil Rights enactment occured in 1875. Charles Lindburgh took his famous flight trip in 1927. The first atomic bomb was dropping in 1945. Therefore, the Civil Rights bill enactment occured first.
Do attractive forces have less hold on electrons farther from the nucleus?
Yes, as electrons get farther from the atomic nucleus they are less attracted to that nucleus, which is exactly what you would expect on the basis of Coulomb's Law, F=q1q2/r2 as the radius of the orbit increases the attractive force becomes decreased.
Who flew the plane that dropped the atomic bomb?
Paul Tibbets flew the Enola Gay and dropped the atomic bomb upon the Japanese city of Hiroshima whereas pilot Charles Sweeney flew Bockscar and bombed Nagasaki with a nuclear weapon .
