Question

What did ernest rutherford's gold foil experiment demonstrate about an atom?each atom is composed of electrons and positive material.the mass of the atom is evenly spread throughout the atom.neutrons are located in the center of the atom.positive charge occupies a very small volume in the atom?

Answer 1

He proved that electrons were composed of positive and negatively charged particles.

Answer 2

positive charge occupies a very small volume in the atom

Step-by-step explanation:

Rutherford’s gold foil experiment showed:

• Most of the alpha particles pass through undeflected meaning that most of the atom is empty
• A fraction of the alpha particles deflect at 90 degrees indicating that there is positive charge in the atom
• Another fraction of alpha particles deflect at angles greater than 90 degree s indicating that most of the atom's mass is confined to the center of the atom.
