Sorry to make a whole new thread instantly,but as you can see both the topics are quite different.

About photoelectric effect i know that it is caused when a Photon with optimum frequency strike an electron and knocks it out of the electrostatic force of nucleus.Now i want to know would not it change an atom into its ion as it will remove the electrons.And therefore make it unstable?If i am correct that in O₂,if photons of optimum frequency strike an Li atom than it will result in the formation of Li₂O.Please wake me up if i am wrong anywhere.

In the solid state the metal just doesn't have its electrons but it's in a sea of electrons from the other atoms in the metal too. Loosing one electron in a sea of electrons is not a big deal.

But You havent answered my question about the oxide of lithium.You said that loosing an electron from a large number of electrons of a metal makes no difference.Then how much loosing of electrons will make a difference from,say 23 gms[1 mole] of Na.
