Question

The gold foil experiment led to the conclusion that each atom in the foil was composed mostly of empty space because most alpha particles directed at the foil

(1) passed through the foil
(2) remained trapped in the foil
(3) were deflected by the nuclei in gold atoms
(4) were deflected by the electrons in gold atoms

Answer 1

Option 1

Step-by-step explanation:

The correct answer is option 1

The gold foil experiment was conducted by Rutherford. This experiment was conducted to study the Atom.

In the experiment Alpha rays from the emitter are passed through gold foil and there was a receiver that was present there to intercept the alpha rays.

The outcome of the result was that most of the alpha particle pass through foil undeflected and very few rays revert back on the original path from the heavy mass present at the center.

Later this heavy mass was known Nucleus.

Hence, most alpha particles passed through the foil.

Answer 2

(1) passed through the foil

Step-by-step explanation:

Ernest Rutherford conducted an experiment using an alpha particle emitter projected towards a gold foil and the gold foil was surrounded by a fluorescent screen which glows upon being struck by an alpha particle.

• When the experiment was conducted he found that most of the alpha particles went away without any deflection (due to the empty space) glowing the fluorescent screen right at the point of from where they were emitted.

• While a few were deflected at reflex angle because they were directed towards the center of the nucleus having the net effective charge as positive.

• And some were acutely deflected due to the field effect of the positive charge of the proton inside the nucleus. All these conclusions were made based upon the spot of glow on the fluorescent screen.
