Answer:
Here is your answer ll
RUTHERFORD CONCLUDED THAT HIS MODEL HAS A LOT OF EMPTY SPACE BECAUSE OF MANY ALPHA PARTICLE PASSED THROUGH THE GOLD FOIL WITHOUT GETTING DEFLECTED. VERY FEW PARTICLE DEFLECTED FROM THEIR PATH WHICH INDICATED THAT IT HAS LITTLE SPACE.

Answer:
Rutherford deduced that the atomic nucleus was positively charged because the alpha particles that he fired at the metal foils were positively charged, and like charges repel. Alpha particles consist of two protons and two neutrons, so they are positively charged. In Rutherford's experiments most of the alpha particles passed straight through the foil without being deflected. However, occasionally the alpha particles were deflected in their paths, and rarely the alpha particles were deflected backward at a 180 degree angle. Since like charges repel, Rutherford concluded that the cause of the deflections of the positively charged alpha particles had to be something within the atom that was also positively charged. Rutherford concluded from his metal foil experiments that most of an atom is empty space with a tiny, dense, positively charged nucleus at the center that contains most of the mass of the atom. He also concluded that the electrons orbit the nucleus like the planets orbit the sun.
