Mass number = protons + neutrons (of specific isotope) average mass of all isotopes( protons + neutrons (of specific isotope), average mass of all isotopes )
Atomic mass = average of mass between all isotopes protons + neutrons(of specific isotope)( average of mass between all isotopes, protons + neutrons(of specific isotope) )
Atomic number = number of protons neutrons electrons protons and electrons( protons, neutrons, electrons, protons and electrons ) in the nucleus

Electrons > < = +( >, <, =, + ) Protons = Anions
Electrons < > = +( <, >, =, + ) Protons = Cations

Period number = Number of energy levels in atom Number of valence electrons( Number of energy levels in atom, Number of valence electrons )
Group number = Number of valence electrons Number of energy levels in atom The maximum number of electrons( Number of valence electrons, Number of energy levels in atom, The maximum number of electrons )
Number of elements in period = The maximum number of electrons The maximum number of protons The maximum number of neutrons( The maximum number of electrons, The maximum number of protons, The maximum number of neutrons ) in each shell

Intermolecular are bonds between within( between, within ) molecules Eg. (Covalent bonds, Ionic bonds Dipole/Diploe, Hydrogen Bond, LDF( Covalent bonds, Ionic bonds, Dipole/Diploe, Hydrogen Bond, LDF ))
Intramolecular are bonds within between( within, between ) molecules Eg. (Dipole/Dipole, Hydrogen Bond, LDF Covalent bonds, ionic bonds( Dipole/Dipole, Hydrogen Bond, LDF, Covalent bonds, ionic bonds ))

Acids: A compound that when dissolved in water, creates hydrogen ions (H+) hydroxide ions (OH-)( hydrogen ions (H+), hydroxide ions (OH-) ) (have a pH lower higher( lower, higher ) than 7)
Bases: A compound that when dissolved in water, creates hydroxide ions (OH-) hydrogen ions (H+)( hydroxide ions (OH-), hydrogen ions (H+) ) (have a pH higher lower( higher, lower ) than 7)

To name an Acid:
Hydrogen ____ide > Hydro____ic acid ____ic acid ____ous acid( Hydro____ic acid, ____ic acid, ____ous acid )
Hydrogen ____ate > ____ic acid Hydro____ic acid ____ous acid( ____ic acid, Hydro____ic acid, ____ous acid )
Hydrogen ____ite > ____ous acid ____ic acid Hydro____ic acid( ____ous acid, ____ic acid, Hydro____ic acid )

Why is Water Weird?
- Water has a higher lower( higher, lower ) melting/boiling point compared to similar substances
- Water has a high low( high, low ) specific heat capacity
- Ice is less more( less, more ) dense than liquid water
- Water has a high low( high, low ) surface tension
- Water is cohesive and adhesive adhesive cohesive( cohesive and adhesive, adhesive, cohesive )
- Water is neutral acidic basic( neutral, acidic, basic )

Endothermic: More energy is absorbed released( absorbed, released ) to break bonds than is released absorbed( released, absorbed ), so the environment loses gains( loses, gains ) energy (gets colder hotter( colder, hotter ))
Exothermic: More energy is released absorbed( released, absorbed ) than the energy absorbed released( absorbed, released ) to break the bonds, so the environment gains loses( gains, loses ) energy (gets hotter colder( hotter, colder ))
