Byjus structure of atom class 11

WebAtom is the smallest unit of matter and has all the chemical properties of a matter. Atom has a positively charged nucleus, which contains positively charged particles known as protons and neutral particles called neutrons. The nucleus is surrounded by negatively charged electrons. WebSolution. Before the Discovery of Neutron the atomic mass of the elements was found to be double or more than double of the number of protons. Since, the mass of an electron is negligible, It was ambiguous about where the rest of the mass is coming from. For example, if we consider the Carbon atom mass number of Carbon is 12 but the number of ...

WebThe number of protons and neutrons combine to give us the mass number of an atom. It is represented using the letter ‘A.’. As both protons and neutrons are present in the nucleus of an atom, they are together called nucleons. For example, an atom of carbon has 6 protons and 6 neutrons. Thus, its mass number is 12. WebPostulate 1: An atom consists of a positively charged sphere with electrons embedded in it Postulate 2: An atom as a whole is electrically neutral because the negative and positive charges are equal in magnitude …

WebBased on the above observations and conclusions, Rutherford proposed the atomic structure of elements. According to the Rutherford atomic model: The positive charge and most of the mass of an atom is concentrated in an extremely small volume. He called this region of the atom as a nucleus. WebThe existence of a neutral particle in the nucleus of an atom was discovered by James Chadwick. These particles are known as Neutrons. Neutron is a fundamental particle of an atom having no charge and it has a mass almost equal to a hydrogen atom ( 1. 675 × 10 - 31 kg). Neutrons were discovered by James Chadwick.
