relative energies

Single electron atoms - The relative energies of various orbitals of single electrons depend on the value of the principal quantum number 'n' and is independent of the value of 'l'. This can be shown by an arrangement known as energy level diagram. The diagram given be..

In the case of bonding molecular orbital, the attraction of both the nuclei for both the electrons is increased. This results in lowering of energy. In the case of antibonding molecular orbital, the electrons try to go away from the nuclei and this corresponds to repulsive state. The ..

Einstein derived a formula given the relation between mass and energy as E = mc 2 . Here 'm' is the mass, 'c' is the velocity of light and 'E' is the energy. This equation has given equal states to mass and energy. It states that a mass m has energy..

The unit in which atomic and nuclear masses are measured is called atomic mass unit (a.m.u). 1 a.m.u is defined as 1/12 t h of the mass of an atom of 6 C 1 2 isotope. It can be shown that 1 a.m.u = 1.66 x 10 2 7 kg. According to Einstein, mass energy equivalence E = mc 2 Where m = 1.66 x ..

Einstein's Mass-Energy Equivalence Relation - According to Newton's second law of motion, force acting on a body is defined as the rate of change of its momentum i.e., Now, if this force 'F' displaces the body through a distance dx, its energy increases by According to..

In this theory, the rate constant is related to three factors Z, f and p by the equation k = Zfp..

. Rainwater, which seeps into the ground and slowly percolates down through cracks in the upper crust, also gets heated by the hot rock beneath. In certain areas below the earth's surface, hot magma swells up into the crust, but remains trapped below the surface of the earth. Such areas in the eart..

. If we compress or extend a spring, we do work to change the relative locations of the coils within the spring. The result of the work done by our force, is an increase in the elastic potential energy of the spring.Consider the example of two charged particles, A and B. A is po..
