Question

How proton , electron , Newton, and nucleolus discovered

Answer 1

In 1911 Ernest Rutherford who performed many experiments to explore radioactivity did an experiment in which he discoveredthat the atom must have a concentrated positive center charge that contains most of the atom's mass. He suggested that the nucleus contained a particle with a positive charge the proton.

Electron was discovered by J. J. Thomson in 1897 when he was studying the properties of cathode ray. Thomson won Nobel Prize in 1906 for discovering the elementary particle electron.

The motion of an aircraft through the air can be explained and described by physical principals discovered over 300 years ago by Sir Isaac Newton. ... Some twenty years later, in 1686, he presented his three laws of motion in the "Principia Mathematica Philosophiae Naturalis."

Nucleolus- located in the center of the nucleus An Italian scientist named Felice Fontana discovered thenucleolus in eel cells in the year 1774. In 1964, John Gurdon and Donald Brown discovered cell nucleoli in Xenopus laevis (African clawed frog) eggs.
