WebCorrect options are A) and C) According to Rutherford's model of an atom: There is a positively charged centre in an atom called the nucleus. Nearly all the mass of an atom resides in the nucleus. The electrons revolve around the nucleus in circular paths. The size of the nucleus is very small as compared to the size of the atom. WebMuch later Rutherford proved that alpha rays are nuclei of helium atoms by collecting the rays in an evacuated tube and detecting the buildup of helium gas over several days. A third kind of radiation was identified by French chemist Paul Villard in 1900.

Rutherford's atomic model became known as the nuclear model. In the nuclear atom, the protons and neutrons, which comprise nearly all of the mass of the atom, are located in the nucleus at the center of the atom.
WebThe nuclear model of the atom, showing electrons in shells Further experiments led to the idea that the nucleus contained small particles, called protons . Each proton has a small amount of ... WebIn 1911, Ernest Rutherford discovered that at the core of every atom is a nucleus. Atomic nuclei consist of electrically positive protons and electrically neutral neutrons. These are held together by the strongest known fundamental force, called the strong force. The nucleus makes up much less than .01% of the volume of the atom, but typically ...
WebWhat Hold's The Atomic Nucleus Together? The Atomic Nucleus As the atomic model was developed by scientists, what was not clear was how the protons stayed together tightly packed into such a small volume, as defined by the small chargeradius of the nucleus. WebNuclei are made of positively charged protons and electrically neutral neutrons held together by a nuclear force. This force is much stronger than the electrostatic force that binds electrons to the nucleus, but its range is limited to distances of the order of 1 x 10 -15 meters. See Figure 1.
WebThe Bohr Model is a structural model of an atom. The model was proposed by physicist Niels Bohr in 1913. In this model, the electrons travel around the nucleus of an atom in distinct circular orbits, or shells. The model is also referred to as the planetary model of an atom. The electrons orbit around the nucleus similar to how planets orbit ...
