**Step-by-Step Solution:** 1. **Understanding Energy Levels:** - Atoms have different energy levels, often referred to as shells or orbits. The closest shell to the nucleus is called the K shell, followed by the L shell, and so on. Each shell has a specific energy associated with it. 2. **Identifying the Transition:** - In the question, we are considering the transition of an electron from the K shell (which is the first energy level) to the L shell (the second energy level). ...

  • When electron jumps from L to K shell

    A
    energy is released
    B
    energy is absorbed
    C
    energy is sometimes released and sometimes absorbed
    D
    energy is neither absorbed nor released.

  • Statement -I : Energy emitted when an electron jump from 5rarr2 (energy level) is less than when an electron jump from 2rarr1 in all 'H' like atom. Statement -II : The|total energy dofference| between 1^(st) & 2^(nd) energy level is greater than that of any two energy level provided level 1 is not part of those two energy levels.

    A
    If both Statement -I & Statement -II are True & the Statement -II is a correct explanation of the Statement
    I.
    B
    If both Statement -I & Statement -II are True but the Statement -II is not a correct explanation of the
    Statement- I.

    Ionisation energy is the energy absorbed whereas electron affinity is the energy released. Explain.

    (1) As long as an electron revolves in a particular orbit , the electron does not lose its energy Therefore, these orbits are called stationary orbits and the electrons are said to be in station-ary energy state (2) Each orbit or shell is associated with a definite amount of energy . Hence , these are also called energy levels An electron jumps from a lower energy level to a higher energy level , by absorting energy . It jumps from a higher energy to a lower level by emmitting energy in the form of electromagnetic radiation Electrons move around the nucels in specified circular paths called orbits or shells or energy levels and are designated as K,L,M and N shells respectively Arrange the above postulates of Bohr's theory in a correct sequence
