From the chair conformation, rotate about the carbon-carbon bonds of the ring to form a boat conformation. In the boat conformat
ion carbon atoms 1 and 4 are both above (they could also both be below) the plane described by carbon atoms 2, 3, 5 and 6. Look through each of the C-C bonds in the cyclohexane ring. Do you observe any eclipsing interactions?
The atomic number is the same as the amount of electrons and protons. For example: Oxygens atomic number is 8 so the proton and electron count is 8. Hydrogens atomic number is 1 so the proton and electron count is 1.
