Leonard Wolfe · Answer 1

Answer : Option 1) An atom is mainly empty space, and the nucleus has a positive charge.

Explanation : The gold foil experiment done by scientist Rutherford revealed that atoms are the smallest unit of any element which consists of large empty space in it with the nucleus was concentrated in the center of the atom with mostly positive charge around it and virtually contains all the mass of the atoms and there are also negatively charged electrons which revolves in orbits around the nucleus.

Clinton Bender · Answer 2

The answer is 3.

During this experiment, Rutherford aimed a beam of positive particles at a gold foil, expecting all the particles to pass straight through the foil. However, what Rutherford observed was that while some of the particles went through, others were deflected. This demonstrated that a nucleus was present (which is why there's hardly any space in an atom) and that it was positively charged.
