## Homework Statement

Using the uncertainty principle find the energy required for the electron to be confined inside the hydrogen atom. Use the radius of the atom 1 x 10^-10 m for Δr. Express your answer in eV, rounded up to the nearest hundredth.

## Homework Equations

Δx(Δp)[tex]\geq[/tex]h/4pie

x= position in space

p= momentum (mass)(velocity)

## The Attempt at a Solution

ok im not sure how Δr (radius) goes into the uncertainty principle, i know how it works and how it shows that it can not be exactly precise but i just dont understant how Δr would fall in the equation

is it just 1 x 10^-10 m[tex]\geq[/tex]4.14x10^-15 eV/12.56637061?
