Question

part a
rutherfords experiment indicated that matter was not as uniform as it appears. what part of his experimental results implied this idea? explain. drag the terms on the left to the appropriate blanks on the right to complete the sentences.
to explain the deflections rutherford observed, the mass and charge of an atom must all be concentrated in a space that is compared to the size of the atom itself. therefore, it can be concluded that matter must not be as uniform as it appears. it must contain regions of empty space dotted with regions of very dense matter.
you filled in 1 of 4 blanks incorrectly. make sure to indicate the size of regions of very dense matter.

Explanation:

Rutherford's gold - foil experiment showed that most alpha particles passed straight through the gold foil, but some were deflected at large angles. This implies that the mass and positive charge of an atom are concentrated in a small nucleus. The atom is mostly empty space with a small, dense, positively - charged nucleus.

Answer:

To explain the deflections Rutherford observed, the mass and positive charge of an atom must all be concentrated in a space that is small compared to the size of the atom itself. Therefore, it can be concluded that matter must not be as uniform as it appears. It must contain small regions of very dense matter and large regions of empty space dotted with small regions of very dense matter.
