Photoelectric effect.
« on: August 26, 2004, 05:07:11 AM »
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.
Most Common Suggestions I Make on the Forums.
1. Start by writing a balanced chemical equation.
2. Don't confuse thermodynamic stability with chemical reactivity.
3. Forum Supports LaTex

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.
