Re: E=hv
yes it can be used to calculate the energy necessary to remove an electron, but be sure to read the problem closely

Re: E=hv
The equation spelled out is "energy = planck's constant x wavelenght", and since you want to find energy, this equation would be perfect, that is, if you are using it in the correct context.

Re: E=hv
In this case, the equation says that the energy of a particle of light is proportional to its frequency by a constant factor. Therefore, this equation can be used to calculate the energy required to remove an electron.
