Question

what did ernest rutherfords gold foil experiment demonstrate about atoms? their positive charge is located in a small region that is called the nucleus. their negative charge is located in small particles that are called electrons. their nucleus makes up the majority of the volume of the atom. their electrons are floating in a sea of positive charges.

Explanation:

• In Rutherford's gold - foil experiment, most alpha particles passed through the gold foil, but a small number were deflected at large angles.
• This led to the conclusion that the positive charge (and most of the mass) of an atom is concentrated in a small region called the nucleus.
• Electrons are negatively - charged particles. The plum - pudding model (where electrons are floating in a sea of positive charges) was disproven by Rutherford's experiment. The nucleus does not make up the majority of the atom's volume (most of the atom is empty space). And negative charge (electrons) is not in the nucleus.

Answer:

Their positive charge is located in a small region that is called the nucleus.
