positively charged electrons distributed in a uniform negative charge

alpha particle's negative charge and random distribution of protons
alpha particle's negative charge and random distribution of protons

Answer 1

In the design of the gold foil experiment, Ernest Rutherford used the property of **alpha particles' positive charge**. The alpha particles were emitted from a radioactive source and directed at a very thin foil of gold. Rutherford was investigating the structure of the atom and the distribution of positive charge within it.

The correct response among your options is:

**alpha particle's positive charge and electron's negative charge**
