scattered inside
the sphere had a what charge
positive

JJ Thompson
Who did the gold foil experiment
Earnest Rutherford
What did Rutherford want to test in the gold foil experiment
the plum pudding model
what happened to most alpha particles in the gold foil experiment
went straight through
what did the atoms going straight through show in the gold foil experiment
that the atom is mostly empty space
a few alpha particles were reflected at large angles in the gold foil experiment showing what
nucleus is positive
a few particles bounced back in the gold foil experiment showing what
the nucleus is small and dense
what was the gold foil experiment evidence for
nucleus
who made the nuclear model
earnest rutherford
in the nuclear model, rutherford figured that the mass of an atom is
positively charged
What did Neil Bohr discover in the Bohr Model
