1 rutherford scattering

What is a.m.u. expressed in MeV?

• 930.4

• 931.6

• 932.5

• 931.5

The Rutherford scattering experiment led to

• the discovery of the electron.

• the quark model of hadrons.

• the discovery of the nucleus.

• evidence for wave-particle duality.

In the Rutherford scattering experiment most α particles passed through the foil undeflected. What is a correct deduction from this result?

• Most of the mass of an atom is within the nucleus.

• The diameter of the nucleus is much less than the diameter of the atom.

• The nucleus has a positive charge.

• The charge of the atom is neutral.

Rutherford used what type of radiation to bombard the gold foil?

• alpha particles.

• beta particles.

• gamma radiation.

• neutrinos.

Which is a finding attributed to Rutherford's Gold Foil Experiment?

• atoms are indivisible and have a dense positive nucleus.

• atoms are divisible and have multiple layers of electrons scattered uniformly about the atom.

• atoms are like plum pudding with positive and negative charges uniformly scattered throughout the atom.

• atoms are mostly empty space with a dense positive nucleus.

How many protons does gold atom have?

• 197
• 79
• 118
• 276

What was the main conclusion of the Alpha Scattering Experiment?

• Atoms are mostly empty space.

• Atoms are solid and indivisible.

• Atoms are made up of only protons and electrons.

• Atoms are made up of only neutrons and electrons.

What did Rutherford use as a target in his Alpha Scattering Experiment?

• Aluminium foil.

• Gold foil.

• Silver foil.

• Copper foil.

What happens to most of the alpha particles in the Alpha Scattering Experiment?

• They are absorbed by the foil.

• They are deflected back to the source.

• They pass straight through the foil.

• They are deflected at small angles.
