Question

When alpha particles are used to bombard gold foil, most of the alpha particles pass through undeflected. this result indicates that most of the volume of a gold atom consists of?

Answer 1

When alpha particles are used to bombard gold foil, most of the alpha particles pass through undeflected. This result of the experiment indicates that most of the volume of a gold atom consists of unoccupied spaces. This was an experiment done by Ernest Rutherford which allowed him to verify the presence of the a small region positive charge in an atom which is called as the nucleus of the atom. Most of the alpha particles pass through the foil while a certain amount were deflected. Those that pass through confirmed that there is a large area that is unoccupied in an atom.

Answer 2

The model of the atoms and their constituent was given in the  Rutherford model by Ernest Rutherford to prove the plum pudding model of the atomic arrangement to be wrong.

This result demonstrates that most of the space of a gold atom consists of unoccupied space.

What was in the gold foil model of the atom?

A thin foil made up of gold was irradiated with alpha $(\alpha)$particles to demonstrate the position and the features of the atoms and their constituents.

From the experiment, it was deduced that the positively charged matter was present closely in a small dense middle place of the atom called the nucleus.

The electron being negatively charged revolves around the nucleus in an orbit. Many spaces are left in the atomic model which is why the positively charged alpha particles went straight without getting deflected.

Therefore, unoccupied spaces is the correct blank.
