Average number of photons in a atom at a given temprature

AI Thread Summary
The discussion centers on the misconception that atoms contain photons, clarifying that atoms have electrons that can become excited by absorbing photons. It emphasizes that temperature is a statistical property applicable to a collection of atoms rather than an individual atom. The inquiry about how many photons at a wavelength of 1000 nm are needed to achieve a certain temperature is addressed, noting that temperature relates to energy levels of many atoms, not a single atom. Additionally, it is highlighted that energy can come from various sources, not just photon absorption. Ultimately, the conversation reinforces the distinction between photons and the properties of atoms.

Can anny body tell me how do I find the average number of photons in an atom at a given temprature for say lead.

Atoms do not contain photons.Ever.
 
Atoms contain electrons and when an electron is in an excited state it is due to it having taken on an photon. I will like to know how many such photons there are at a given temprature.
 
Let me refrase my question how many photons at a wavelength of 1000 nm does it take to get a atom to a certan temprature.

It does NOT mean that atom contains photons. Absorbed photons do not exist enymore.

This does not make sense either, since temperature is a statistical property of a large numer of atoms, not one atom.

Individual atoms do not have a temperature, as temperature is a statistical property that only applies to systems (objects) composed of many atoms.

Electrons are excited when the atom absorbs a specific quantity of energy, regardless of where that energy came from. It could come from absorption of a photon, a collision with another atom, an interaction with a subatomic particle, etc.

Do you mean certain energy level? Since an atom won’t have temperature, only lots of atoms will have temperature.
