This is my problem in my chemistry class. It's a project we have to do over the weekend. I have been listening and taking notes of everything in our class that our teacher says or writes on the board and I still do not understand this problem.(adsbygoogle = window.adsbygoogle || []).push({});

Using Models Niels Bohr proposed that electrons must occupy specific, quantized energy levels in an atom. He derived the following equations for hydrodgen's electron orbit energie (En) and radii (Rn).

Rn = (0.529 x 10 ^-10 m) n2

En = -(2.18x10 ^-18 J)/n2

* ^ indicates an exponent.

Analysis

Using the orbit radii equation, calculate hydrodgen's first 7 electron orbit radii and then construct a scale model of these orbits. Use a compass and a metric ruler to draw your scale model on two sheets of paper that have been taped together. Using the orbit energy equation, calculate the energy of each electron orbit and record the values on your model.
