b. Ernest Rutherford

a. Nucleus doesn't have any charge. It's neutral

Answer 2

Ernst Rutherford Discovered Nucleus

Explanation:

a.) A nucleus being the base of an atom has positive (+) charge, and it is surrounded by 1-2 electrons (Negatively charged particles (-))

We know that, In any nucleus,

• Number of Protons = Number of Electrons

Hence, this rule gives atom Neutral Charge (Zero - 0 Charge)

b.) Nucleus is small

It is Dense and has Neutrons along with protons in the middle, this was found by Ernst Rutherford in 1909.
