E=A X (1/ni2+1/nf2)

What is A?

E=A X (1/ni2+1/nf2)

What is A?

That looks more like Rydberg than Bohr. Where did you find it? And I haven't seen an equation relating the energy levels of electrons and two variables like taht. Unless one of the variables is the -13.6eV constant?

It is the Bohr equation.

 

[Kaustikos]

It is the Bohr equation.

But where did you find it?

Maybe just forget what I have written above.

Does anyone know the Bohr Equation?

Does anyone know the Bohr Equation?

Yes

E = -Rh [(1/n2)-(1/n2)]

THAT is the Bohr equation. I wouldn't memorize what you found because I can guarantee that if the MCAT were to ask you a question on the Bohr model/equation, the above would be used.

What is Rh?

 

[Kaustikos]

What is Rh?

Rhydberg constant. Which, upon further derivation, can lead to the -13.67 eV. I don't know the exact number off the top of my head, though.

Yeah. A = -Rh

Rydeberg Constant. Its also equal to -13.6 eV. Its the amount of energy an electron holds, or that the nucleus allows at its ground state I believe? I'm guessing though.
