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.

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 did Rutherford have to say about the structure of the atom?
Rutherford proposed that the atom consists of a small, positively charged nucleus surrounded by negatively charged electrons orbiting around it. He conducted the gold foil experiment which led to the discovery of the nucleus and the proton.
Who explained the behavior of positively charged particles being deflected from a metal foils as the nucleus?
Ernest Rutherford explained the behavior of positively charged particles being deflected from metal foils as they interacted with the nucleus of the atom in his famous gold foil experiment. This experiment led to the discovery of the atomic nucleus as a small, dense, positively charged center within the atom.
How did he know that the nucleus was positively charge?
Ernest Rutherford inferred that the nucleus was positively charged through his famous gold foil experiment in 1909. When he bombarded a thin sheet of gold with alpha particles, most passed through, but a small fraction were deflected at large angles. This unexpected deflection indicated that a dense, positively charged center (the nucleus) was present within the atom, repelling the positively charged alpha particles. This led to the conclusion that the nucleus must contain a positive charge to account for the observed scattering.
Rutherfords conclusion of the structure of an atom?
Rutherford concluded that an atom has a small, dense nucleus at its center, surrounded by orbiting electrons. The nucleus contains positively charged protons, with neutral neutrons also present. This model is known as the nuclear model of the atom.
Small dense positively charged nucleus?
Yes.
What Small positively charged particles are found in the nucleus?
Protons.
What did Ruthford's Gold Foil Experiment provide evidence for?
Rutherford's Gold Foil Experiment provided evidence for the existence of a small, positively charged nucleus at the center of the atom. This discovery led to the development of the nuclear model of the atom and overturned the previous plum pudding model.
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?
The gold foil experiment convinced Ernest Rutherford that the atom has a small positively charged nucleus. In this experiment, alpha particles were shot at a thin gold foil. The fact that some of the alpha particles were deflected and even bounced back led Rutherford to conclude that atoms have a small, dense, positively charged nucleus.

What did Rutherford proposed with regards to the structure of atoms?
Rutherford discovered the atomic nucleus and the proton. Rutherford don't discovered the atom. 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.
