Answer:

A good explanation is the “Ideal State for Electrons”, like the Noble Gases; but unlike these Noble Gases, with filled outer Shells of electrons, Halogens are -1, and other elements, +1 and so on, so the most stable, and filled electron shells can be created.

When the excited electron in a hydrogen atom falls from to , a photon of blue light is emitted. If an excited electron in falls

Dima020 [189]

Answer:

n = 3 for similar blue light

Explanation:

The principle applied here is energy levels and energy changes. There are different energy levels depending on the value of the integer as explained by Max planck - a german physicist in 1900, Max planck claimed that electrons in an atom were presumed to be oscillating with a frequency f, then there enrrgy will be given by the plancks equation ; E =hf, where h is the plancks constant.

In general energy of each level can be written as E =nhf
