Ernest Rutherford was born on August 30, 1871.
Ernest Rutherford's gold foil experiment demonstrated that atoms have a small, dense nucleus at their center that contains positively charged protons. This nucleus is surrounded by mostly empty space where negatively charged electrons are found orbiting. This experiment led to the development of the nuclear model of the atom.
The conclusions were that the nucleus in an atom must:- (1) Be positive as it repelled the positive alpha-particles (2) Have a high mass, as the deflections were massive (3) Be very small as only a few of the particles were deflected
Thomsons model is sometimes called the plum pudding model as he envisaged a soup of positive charge with negative charges, by then already called electrons swimming round. He came up with this idea in 1904."the atoms of the elements consist of a number of negatively electrified corpuscles enclosed in a sphere of uniform positive electrification"Rutherford following on from the famous scattering experiment with gold foil and alpha particles proposed that the positive charge was concentrated in a central nucleus.
why was Ernest Rutherford's nickname lord Rutherford
Ernest Rutherford, following the "gold foil" experiment.
He was an employed chemist and physicist.
Rutherford found that atoms have a nucleus
it made your mom
i don 't know !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! nmdtmdt
Ernest and Mary gave birth to one daughter named Eileen Mary Rutherford
he found faults in the atomic theory of jj Thompson
Read at this link.
he shot tiny alpha particles throug a piece of gold foil.
The conclusion was that an atom has a nucleus (center) with a positive charge.
Opinions vary. The discovery of the atomic nucleus ("most of the atom is empty space")
