The density of copper is 8.94g/mL. In the lab, a

student found the density to be 7.99g.mL.

What is the percent error?

True – Exp x 100 True(8.94g/mL – 7.99g/mL) x 100 8.94g/mL=10.6%

Explain Bohr’s theory on how light is emitted.

When an electron gains energy it moves further from the nucleus to a

higher energy level, it then falls back down emitted

that energy as light.
