Why are we focusing on the elements H O N C ?

• it's fun to misspell the word honk

• they are the first 4 elements created after the Big Bang

• they are only found on Earth

• they make up the majority of the human body

Why are the atoms attached to Carbon, putting Carbon in the middle of this molecular structure

• Carbon is magnetic

• Carbon has the most mass, thus the most gravitational pull

• Carbon is diamonds

• Carbon can make up to 4 bonds, the most possible

Atoms "want" / strive to have...

• A full outer shell of electrons

• One electron short of a full shell

• 2 valence electrons

• their time in the sun

Why can't Oxygen add one more Hydrogen to make H₃O?

• Mickey Mouse only has 2 ears

• Hydrogen is very negatively charged

• Oxygen can only form 2 bonds
