Bohr Atom Energy Change Example Problem

Bohr Atom Energy Change Example Problem This model issue shows how to discover the vitality change that relates to a change between vitality levels of a Bohr molecule. As per the Bohr model, an iota comprises of a little positive charged core that is circled by contrarily charged electrons. The vitality of an electrons circle is controlled by the size of the circle, with the most minimal vitality found in the littlest, deepest circle. At the point when an electron moves starting with one circle then onto the next, vitality is assimilated or discharged. The Rydberg equation is utilized to discover the particle vitality change. Most Bohr molecule issues manage hydrogen since it is the least difficult iota and the simplest to use for figurings. Bohr Atom Problem What is the vitality change when an electron drops from the n3 vitality state to the 1 vitality state in a hydrogen molecule?
