## Homework Statement

At the bottom of this linked-to screen below is an equation for E = - .......... = - ............. = - 13.6 Z^2 / n^2 eV

https://en.wikipedia.org/wiki/Bohr_model#Electron_energy_levels

## Homework Equations

I'm using the following values for the formula

Z=1

n=1

K sub e = 8.987 x 10^9 (Coulombs constant)

e = 2.71828

m sub e = 9.11 x 10^-31 (mass of electron)

h-bar = 1.05 x 10^-34

## The Attempt at a Solution

But when I plug these values in I get (4.017x10^-9) / (2.205 x 10^-68) = - 1.82 x 10^59

and not -13.6 eV

What am I doing wrong? Are any of my values above incorrect?
