Put this onto your Reference Tables Jan 1

What I'd put onto my reference tables if I were you.
K = C + 273 formula to convert Kelvin to Centigrade or vice versa. Put it into Table A. It's on the back
page, but you forgot that.
Never change a Table E name. Put it under table E, don't forget it's there.
Soluble in water = Aqueous, insoluble in water = precipitate. Put this near Table F.
Acids and Bases are listed from strongest to weakest. Strong acids have lots of H+ ions, strong bases
have lots of OH- ions. NH3 is an exception.
Periodic table notes:
•
molecular compounds = 2 or more non-metals bonded into molecules, a new substance with new
properties. Use prefix method of naming, mono, di, tri, tetra, penta, hexa, hepta, octa, nona,
and deca. CO, CO2, H2O will set up the 1st and 2nd name rules.
•
1st name rule: if a single atom, just say atom name. If the first part is a multiple (2 or more of
same atom) use a prefix for the first name.
•
2nd name rule: always use a prefix, single atoms or multiple atoms. And it’s going to end in -ide.
•
electrons are shared, not transferred, atoms bond together. use oxidation numbers to balance
numbers of atoms to fit together. oxidation numbers must net to zero for a compound to exist
in that ratio.
•
ionic compounds = metal or nonmetal bonding as cations and anions. together the ions must net
out to zero charge for a real compound to form. no left over electrons, or IOU's.
•
metals lose electrons and form + cations. nonmetals gain electrons to become – anions. Cations
transfer their electrons to the nonmetals so both can gain an electron configuration just like a noble
gas (they become isoelectric to noble gases.
•
Never change names on table E polyatomic ions when using them
• If metal is transitional, and it makes multiple possible + cations, use a roman numeral to indicate
which cation is being used in a particular formula.
•
Some transitional metals (Zn, Sc, etc.) make only one cation, have only 1 + oxidation number: NO
roman numerals are needed for them.
•
Metalloids are metals with some nonmetal characteristics, or nonmetals with metallic
characteristics. the 7 metalloids are: B, Si, Ge, As, Sb, Te, At, BUT NOT Al or Po, they’re the
DOG FOOD exceptions because AlPo is a kind of dog food that I put into your hand to remember.
