What evidence is there that the nucleus of an atom is very small and positively charged?

Rutherford's famous gold foil and proton experiment showed that very occasionally a proton fired at a nucleus came straight back at the 'gun'. He likened it to a naval shell being returned after hitting a piece of tissue paper. The fact that so few protons returned or were deflected by the tiny nucleus compared to the billions emitted by the proton 'alpha' source showed that nuclei of gold atoms were small and very widely spaced apart.

What describes and atom?
A negatively charged electron cloud surrounding a positively charged nucleus. Reason: The nucleus contains positively charged protons and neutral neutrons. The positive nucleus is surrounded by a negatively charged electron cloud.
The Is the positively charged central core of an atom?
Nucleus is the positively charged central core of the atom. It was discovered by Sir Rutherford during the alpha particle scattering experiment. But later by Sir Chadwick neutrons were also discovered along with protons in the nucleus. The nucleus is positively charged, small and is heavier than alpha particles.
What part of the atom was discovered by Rutherford?
Rutherford discovered the atomic nucleus and the proton. A short answer for the Rutherford atomic model: the atom is composed from a central part - a nucleus, positively charged, surrounded by electrons - very small negative charged particles.
What did ernest rutherford conclude about the nucleus of an atom?
Rutherford claimed that at the center of an atom there was a very tiny, very dense, positively charged part called a nucleus, surrounded by electrons at a distance.
What part of the atom does the word nuclear refer to?
A concept or model of the atom characterised by the presence of a small, massive nucleus at its centre.
Small dense positively charged nucleus?
Yes.
What Small positively charged particles are found in the nucleus?
Protons.

Who said there's a small dense positively charged nucleus?
Ernest Rutherford
What experiment convinced Ernest Rutherford thet atom has a small positively charged nucleus?
Rutherford used the gold foil experiment to figure out that an atom had charged particles in the nucleus
