A student carried out an experience to study the atoms of gold, a beam of α-particles was directed onto a thin sheet of gold. The results were as follows:
i. Majority of the particles went through undeflected.
ii. A few particles deflected through varying angles up to 180⁰.
What inference can be made from these observations about the structure of the atom?

a-particles are positively charge. If
i. Majority were undeflected this implies that the nucleus is small.
ii. Few deflection implies that the nucleus contains some positive charge
