Why use flame photometry is applicable only to s- block elements?

Flame tests are a common way of identifying trace amounts of alkali metals (and to a lesser extent alkaline earth metals) in mixtures. Certain salts of Ba,SrBa,Sr are also used in fireworks for their ability to impart a colour to the flame.

Although predominant among s block elements this behaviour is also seen in other elements like CuCu and PbPb.

✨✨Hi mate✨✨

s-block elements have 1 or 2 electrons in valence shell.When heated...electrons are excited to higher unoccupied orbitals....As the electrons fall back due to unstability they emit photons of wavelength in the visible region.

✨✨✨✨Hope this helps✨✨✨✨
