dumb chem doubt
may sound dumb but i have a doubt. when we heat up a metal , say a metal pan on stove , we are essentially supplying energy to the electorns. what if the electrons get enough energy to jump out of their orbit ? where will they go? in the environment or what

Hello @hardcoreisdead!
Choose the Study Helper subject ping
Choose the subject for the respective doubt :)
It wouldn't be possible in case of stove, but a thing called ionization energy exists.
Ionization energy is the energy required by a certain atom to remove a electron from its orbitals and make the atom a cation.
You will study this topic in class 11th "Periodic Classification of elements" in detail.
but ionization energy is for gases only
what about work function of a solid metal??
also why would it not work in case of stove
do you need a ping?
My metal is hypothetical, just imagine that is possible
My question really isn't about the energy but the electron who escaped due to getting the energy
To make it sound more realistic we may take a solid metal in a crucible
You do know that the electrons are pretty much instantly replaced post photoelectric effect
right
But thats when they are in that tube of experiment where they are attracted by the positive plate (receiver plate?and then returns to the ejector plate leading to photocurrent
Again what makes you think that's the only way of emissions of electrons
Electrons can be ejected and received in multiple ways
Yeah that's my point , electrons only need energy, be it in any form , photon mein ya heat mein it doesn't matter
What if the photoelectric effect is taking place in natural environment, like sunlight falling on an electric pole with a work function really low
There's no receiver plate right
Many of the times the electron goes back to the metal
And a photon is ejected right
Howw? It gets a kinetic energy in the outwards direction how can it come back
Attraction b/w the molecule and free electron
ohhh, so that explains my heat doubt too ig
Lol also about the environment thing. Ejecting a valence electron to infinity essentially means a huge distance such that it cannot get attracted back anymore which can be 1 cm as well because that already is a huge distance for an electron so sure it won’t go to Saturn or somewhere else lmao
Hmm I do get it
But woh 1 cm bhi bahar aake kya karega
Ik I might sound dumb or smthing but it just doesn't fit
Depends on what conditions you ionize them
Agar positive charged plate hai metal ke paas toh photoelectric current is made
Agar vacuum hai toh electron cloud banta metal ke paas (it’s called space charge)
Abb hawe mein hi kroge toh they might just fly away and get accepted by an electron deficient species in the vicinity.
woahhh, thats the answer i was looking for
