Q. Outer orbits have _____ energy level than inner orbits.

Q. What idea states that lower energy level orbitals will be filled with electrons before higher energy level orbitals?

Q. (a) 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 stationary energy states.
(b) Each orbit or shell is associated with a definite amount of energy. Hence these are also called energy levels.
(c) An electron jumps from a lower energy level to a higher energy level, by absorbing energy. It jumps from a higher energy level to a lower energy level, by emitting energy in the form of electromagnetic radiation.
(d) Electrons move around the nucleus in specified circular paths called orbits or shells or energy levels and are designated as K, L, M, N shells respectively.

Arrange the above postulates of Bohr's theory in a correct sequence:

For a Sodium atom, the Valence electron lies in the ___shell/energy level.
