Arrangement of Electrons in an Atom (Bohr-Bury Scheme) - Electrons revolve around the nucleus in different energy levels or shells and each shell is associated with definite energy. The energy of the K shell is the least while those of L, M, N and O shells increases progressivel..

Maximum number of electrons that can be accommodated in a shell is given by 2n 2 where n = shell number For 1 st energy level, n = 1Maximum number of electrons in 1 st energy level = 2n 2 2 x (1) 2 = 2 For 2 nd energy level n = 2Maximum number of electrons in the 2 nd energy level = 2n..

Electrons revolve around the nucleus in different energy levels or shells and each shell is associated with definite energy. The energy of the K shell is the least while those of L, M, N and O shells increases progressively. We also know that any system that has least energy is the most stable.1 s..

How a Laser Works - The below figure shows schematically how a population inversion can be achieved so that laser action-or lasing us it is called can occur. Atoms from the ground state E 1 are "pumped" up to an excited state E 3 , for example by the absorption of light energy from an int..

The workers in a manufacturing company are hired on a daily wage scheme. The table represents relation between the number of days a worker works and his wages paid. Which of the following rules represents the relationship? Number of days Wages paid 6 35 8 47 14 83 24 143 => Wage..

The arrangement of electrons in the various shells/orbits/energy levels of an atom of the element is known as electronic configuration. Keeping the Bohr and Bury rules in mind let us write the electronic configuration of elemen..

Energy - Energy is a number that we associate with a system of one or more objects. If a force acts on one of the objects, making it move, then the number changes. After countless experiments, scientists and engineers realised that if the scheme by which we assign these energy numbers is ..

Neils Bohr was a eminent Danish Physicist who obtained his doctorate in theoretical Physics in 1911. He made a great contribution towards the understanding of atomic structure and quantum mechanics. He was awarded the Nobel Prize in Physics at the young age of 37, in 1922, primarily for h..

The Aufbau principle states that in the ground state of an atom, an electron enters the orbital of lowest energy first, and then the subsequent electrons are fed in the order of increasing energies into the orbitals. The relative energies of various orbitals are given in fig.1.6. From the figure, t..
