What Rutherford discover in his gold foil experiment?

Answer 1

He found that the atom was made up of mostly empty space.

Answer 2

Rutherford discovered that atoms are mostly empty space except for the nucleus at the center of the atom.

Answer 3

A short answer for the Rutherford atomic model: the atom is composed from a central part - a nucleus, positively charged, surrounded by electrons - very small negative charged particles.

Also Rutherford discovered atomic nucleus and the proton.

Answer 4

Rutherford's three observations: # Most alpha particles passed stright through the foil. # Some were deflected through angles less than 90 degrees. # A very small proportion of particles were deflected through angles greater than 90o. His three subsequent conclusions: # Most of the atoms are empty space. # The alpha particles have an overall positive charge, forcing them to be repelled away from the metal atoms in the foil. # The atoms in the foil have a large, dense nucleus in their centres.

Answer 5

Rutherford discovered the atomic nucleus and the proton.

Answer 6

He discovered that some alpha particles were deflected by atoms. From this he concluded that the popular "plum pudding" model of an atom, where people thought that an atom was a positive particle filled with smaller negative particles, was wrong. Instead he created the atomic model which has a nucleus (neutrons and protons) surrounded by much smaller electrons.

Answer 8

protons are located in the nucleus of an atom

Answer 9

He discovered the nucleus.
