It is introduced by Danish Physicist Niels Bohr in the year of 1913. According to this model the atom consists of small nucleus at the center and electrons which rotates in circular orbits surrounding the nucleus – similar to solar system. But here, the force of attraction is provided by electrostatic forces rather than gravitational forces. The nucleus is positively charged and electrons are negatively charged. Further Niels Bohr illustrated that the positively charged nucleus consists of proto

We all have seen plums in padding. Previously it was thought that electrons in an atom are distributed on positive charge just like plums in a pudding. In other words, it was thought that positive charge exists throughout the atom and negative electrons are unevenly distributed on it just like plums in the pudding. This concept of the atomic model is so known as plums in pudding model of atoms. This concept was introduced by J.J.Thomson who was also the inventor of electrons. As according to plu

he electronic configuration of an atom is a way of describing how its electrons are arranged in different energy levels and sublevels around the nucleus. The electronic configuration of an atom determines many of its physical and chemical properties, such as how it reacts with other atoms, how it conducts electricity, and how it behaves in a magnetic field.What is an Electron?An electron is a negatively charged subatomic particle that orbits the nucleus of an atom. The nucleus consists of positi

What is the Plum Pudding Model?Aplum pudding modelis a historical scientific model of the atom that was proposed by J.J. Thomson in 1904, shortly after he discovered the electron. The model tried to explain two properties of atoms that were known at that time: electrons are negatively charged particles, and atoms have no net electric charge.The plum pudding model suggested that an atom consists of a sphere of positive charge, called the pudding, with electrons embedded in it, like plums in a des
