Re: Chemistry Notes For AIPMT
As you have asked about the chemistry notes for AIPMT, I am providing you with it Atomic Structure In 1809, Dalton suggested that atom is the smallest particle of the element and it is indivisible. But in the beginning of 20th century Rutherford, J.J. Thomson and more suggested that atom is divisible and made up of electrically charged particles. Electron The electron is a fundamental particle of an atom which carries a unit negative charge. It was discovered by J.J. Thomson in 1897. Proton It is a fundamental particle of an atom carrying a unit: positive charge. It was discovered by Rutherford and Goldstein in 1886. Neutron It is a fundamental particle of an atom carrying no charge. It was discovered by Chadwick in 1932. Properties of Cathode Rays They travel in straight: lines. They cast shadow of solid objects placed in their path. They cause mechanical motion, i.e., they consists of material particles. They carry negative charge. These rays are deflected when magnetic field is applied on them. They produce heating effect. They cause ionization of gas through which they pass. They affect the photographic plates. They have penetrating power. Chemistry notes for AIPMT |
