Dalton model
John Dalton lived from September 6, 1766 on to July 27, 1844. He was an English chemist, meteorologist and physicist. John Dalton pictures atoms as small, indestructible particles with no interal structure. -
Thomson model
JJ Thomson was a British physicist and Nobel laureate. He won the Nobel Prize in Physics. He lived from December 18, 1856 to August 30, 1940. He thought electrons was tightly surrounded in a sphere of positive electrical charge. The Thomson model is also called the plum pudding model. -
Hantaro Nagaoka
A Japanese physicist named Hantaro Nagaoka suggested that a atom has a central nucleus. Electrons move in orbits like the rings aroud Saturn. He was the world’s first scientist to present a Saturnian model of the atom. -
Rutherford model
Ernest Rutherford was born in New Zealand. He is a British chemist and physicist who became known as the father of nuclear physics. He found out that an atom has a small, dense, positively charged nucleus. Rutherford was born on August 30, 1871 and died on October 19, 1937. -
Bohr model
Niels Henrik David Bohr was the person who found this model. He was awarded the Nobel Prize in Physics in 1922. He was born on October 7, 1885 in Copenhagen and later died on November 18, 1962 in the exact same place he was born. The electron moves in a circular orbit at fixed distances from the nucleus. -
Electron cloud model
Erwin Schrodinger was the person who found this model. Erwin's whole name was Erwin Rudolf Josef AlexanderSchrodinger. He was born on August 12, 1887 and died on January 4, 1961. But, he develops mathematical equations to describe the motion of electrons in atoms.
