The meaning of a symbol in Atomic Theory

[Final_HB]

I happened across this little thing in a formula and I can't find what it stands for in any book/ website I think it stands for the ground state of an element, but I want to clarify first

The symbol is E₀

Its in this formula, which is derived from the energy of an electron.

E₀ = \frac {e^4 m} {32 \pi^2 \ hbar^2\epsilon^2}

 

[Doc Al]

Yes, that's the energy of the ground state of a hydrogen atom, in the Bohr model.

 

[Final_HB]

Thats perfect thank you :)

And then, I am assuming, E_1 would be the next energy state and so on.

 

[Khashishi]

E_1 depends on context. It could mean an adjustment in the energy in perturbation theory.

 

[Final_HB]

well... in the context of the energy of an electron

 

[Khashishi]

That's not enough context.

 

[Integral]

Thats perfect thank you :)

And then, I am assuming, E_1 would be the next energy state and so on.

If you define it that way, yes. The author of the book or paper should define his terms. There are only a few that are universal.
