The atom scientists in the mid - 1920's , by the convinced that the Bohr atomic model was incorrect , formulated new and innovative explanation of how electron are arranged in atoms.

The english scientist Henry Moseley ( !887 - 1915 ) discovered that atoms of each element contain a unique positive charged

Each demonstrated a connection between atomic mass and the properties of elements .

Ernest Rutherford determines properties of the nucleus , including charge , relative size , and density . 1932 Scientist develop a particle

Who performed the famous gold foil experiment that helped define modern atomic structure , identified alpha , beta , and gamma radiation .

Ernest Rutherford showed in 1911 that the positive pudding was all crammed into a massive dense core , or nucleus , surrounded at a distance by the electron plums .

Each demonstrated a connection between atomic mass and the properties of elements .

Who performed the famous gold foil experiment that helped define modern atomic structure , identified alpha , beta , and gamma radiation .

Bohr ‘s role in the enterprise being in 1913 with a series of three papers that became the foundation for the future of atomic science .

Published a theory of atomic structures relating the electron arrangement in atoms and atomic chemical properties

Proved the existence of neutrons

A model of atomic structure Proposed by J . J. thomson

One of the first to use an analytical balance to monitor chemical reactions

He was a school teacher in england

He studied chemical reaction and made observations and measurements on the way . He was able to determine the mass ratio of the elements involved in those reactions

believed that everything in the universe was made up of atoms

He discovered electrons and Thomson is also credited with finding the first evidence for isotopes of a stable ( non-radioactive) element in 1913

Determined the charge of an electron using the oil dropping apparatus

Thomson showed that cathode rays were composed of previously unknown negatively charged particles, which he calculated must have bodies much smaller than atoms

He discovered electrons and Thomson is also credited with finding the first evidence for isotopes of a stable (non-radioactive) element in 1913

Determined the charge of an electron using the oil dropping apparatus
