Question

Why are alkali metals most suited as photo sensitive metals?

Answer 1

Answer:

alkali metals are said to be most suitable for the photoelectric effect because the alkali metal have more and more tendency of loosing electrons and hence make it easier for the photon to eject it out from the atom with the consumption of less energy .

Explanation:

mark me as brainliest and hope it helped .

Answer 2

Photoelectric effect is the phenomenon by which the electrons are ejected from the surface of the metal when a radiation of suitable frequency is used. ... They have very low ionization energy so it will be easy to eject the electron from the alkali metals . Thus they are suitable for this effect.
