Answer
According to Rutherford's model of an atom, there is a positively charged mass in the centre of the atom, i.e., nucleus, in which the entire mass of the atom is concentrated, which makes nucleus the densest part of the atom. The electrically positive nature of the nucleus is supported by the fact that the positively charged α-particles approaching the nucleus get deflected. This proved that nucleus contained protons.
