Ionic bonds Metal and non metal generally higher melting and boiling points
The octet rule is a rule were the atoms want to have a full outer shell with 8 electrons the exception is hydrogen
The 7 diatomic molecules are Oxygen, Nitrogen, Hydrogen, Florine, Chlorine, Bromine, and iodine they naturally bond together in nature.
A polar bond can have a difference in Electronegativity If the difference is great enough it can actually be an ionic bond
Single bond 2 electrons Double bond 4 electrons triple bond 6 electrons Polar bond shares electrons and coordinate covalent bond is when an atom shares two electrons!

ionization energy is the energy required to remove one electron form an atom, the amount of energy increases across a period, but decreases down a group because electrons are father away from the nucleus will increase as more electrons are pulled away
Gas Standard Pressure is 1 ATM/101.3kPa 0 degrees Celsius At STP, 1 mole of any gas occupies 22.4L.
