Describes the structure of an atom

WebThe radius of an atom must be defined arbitrarily, such as the boundary in which the electron can be found with 95% probability. Atomic radii are typically 30-300 pm. Figure … WebThe electrons are distributed around the nucleus and occupy most of the volume of the atom. The Bohr model of the atom proposed by Neils Bohr is similar to the planetary motion. Hence this model is also known as the planetary model of the atom. He describes that the negatively charged electrons will orbit around the positively charged nucleus.
