MODULE 01: Common Ions to KNOW!!
This part of the summer assignment is quite simple. Just give yourself enough time to master the formulas,
charges and names of the common ions. On the 2nd day of school, you will be given a quiz on these ions. You
will be asked to:
 Write the names of these ions given the formula and charge
 Write the formula and charge when given the names

“From the Table” Ions: For the ions in Table 1, their placement in the Periodic Table suggest the charge on the
ion, since the neutral atom gains or loses a predictable number of electrons in order to obtain a noble gas
configuration. This was a focus in first year chemistry, so if you are unsure what this means, get HELP BEFORE
the start of the year. Three transition metals are also included (silver, cadmium and zinc). These three
elements will always have the charge given in the table and should be also be memorized. You will have a
periodic table to reference for this ion quiz, so the above ions should be quite easy.
3
Polyatomic Ions: The common ions in Table 2 need to be MEMORIZED. Below are a number of patterns that
can be used to greatly reduced the amount of memorizing one must do.
Hint 1: “-ate” ions have one more oxygen that the corresponding “-ite” ions, but the same charge. If
you memorize the “-ate” ions, then you should also be able to memorize the “-ite” ions quite easily,
and vice versa.
Example: Sulfate is SO42-, so sulfite is the same charge with one less oxygen (SO32-)
Example: Nitrate is NO3-, so nitrite is the same charge with one less oxygen (NO2-)
Hint 2: If you know that a sulfate ion is SO42-, then to get the formula for hydrogen sulfate, you add a
hydrogen ion to the front of the formula. Since hydrogen has a 1+ charge, the net charge on the new
ion is less negative by one.
Example:
PO43→
HPO42→
H2PO4phosphate
hydrogen phosphate
dihydrogen phosphate
Hint 3: Other prefixes: “Per-” indicates one more oxygen than the “–ate” form
“Hypo-” indicates one less oxygen than the “–ite” form
Example: ClO4→ ClO3- → ClO2- → ClOperchlorate
chlorate
chlorite hypochlorite

The Halogens are all the same: F, Cl, Br, I all behave the same, so if chlorate is ClO3- ,
Bromate is …… BrO3- !!!
Hint 4: Make FLASHCARDS to help with your memorization!!

MODULE 02: Rounding & Significant Figures
NOTES: ROUNDING
Definition
Rounding involves reducing the number of digits in a number while still accurately
representing the original number
Example The number 4.9 is very close to 5. For simplicity or accuracy sake, we can round this
number to 5.
What are the
1. You may round to any “place” of a number.
rules?
2. The place you are rounding is followed by a 0, 1, 2, 3, or 4, then you “round down”
to the next number
3. The place you are rounding is followed by a 5, 6, 7, 8, or 9, then you “round up” to
the next number

NOTES: SIGNIFICANT FIGURES
Significant figures are digits in a number that indicate the level of precision of a
measuring device
Example A ruler can only precisely measure based on each tick mark. In the following example,
each tick mark represents 1/10 of a centimeter, or 0.1cm. So, the ruler can only
precisely measure to the first decimal place but you can estimate the 2 nd decimal place
to some degree of “confidence.”
What are the rules?
1. All non-zero (1, 2, 3, 4, 5, 6, 7, 8, 9) digits are ALWAYS significant
2. All zeros are NOT significant, UNLESS
a. Zero is between two other non-zero numbers
b. Zero is at the end of the number AND has a decimal point (anywhere
within the number)
3. Exact values have infinite significant figures. This includes…
a. counting whole numbers (ie, counting the number of students in the
classroom).
b. some known relationships (ie, 12 in = 1 ft)
Adding/Subtracting When adding or subtracting, you must always take the lowest number of significant
figures AFTER the decimal place (or just the number of decimal places)
Multiplying/Dividing When multiplying or dividing, you must always take the lowest number of significant
figures before and after the decimal place
Multi-step Algebra When adding/subtracting AND multiplying/dividing, you must keep track of your
significant figures by rounding after each operation.
Don’t forget your order of operations!

MODULE 03: Naming & Writing Chemical Compounds
NOTES: Naming & Writing Ionic Compounds
An ionic compound is formed between a metal and a nonmetal, or a cation ion (positive
ion) and an anion (negative ion).
How do I know it
is an ionic
compound?
Naming Rule 1: Look at the cation first. If the cation has only one possible charge (Group 1, Group 2, Al,
Ag, Cd, Zn)
 Write cation first
 Write anion last ending in –ide
Examples: 1) CaCl2
 Look at Ca first! ← Ca is in group 2 (only can have a charge of 2+)
 Chlorine become Chloride
= Calcium Chloride
2) Al2O3 = Aluminum Oxide
Naming Rule 2: Look at the cation first. If the cation has more than one possible charge (most transition
metals, post-transition metals)
 Write cation first, write cation charge (as Roman Numeral) in parentheses
 Write anion last ending in –ide
 Charge of cation is based on charge balance
Examples:
1) FeCl3
o Look at Fe first! ← Fe is a transition metal (can have a charge of 2+ or 3+)
o To determine charge of Fe → look at Cl
o Cl has a charge of 1o There are 3 Cl1- → overall negative charge of -3
o To balance a negative three, you must have a positive three
o Fe must have a charge of 3+ →Iron(III)
= Iron (III) Chloride
2) Cr2S3
o Look at Cr first! ← Cr is a transition metal (can have a charge of 2+ or 3+)
o To determine charge of Cr → look at S
o S has a charge of 2o There are 3 S2- → overall negative charge of -6
o To balance a negative six, you must have a positive six
o The overall charge of Cr is +6, but there are 2 Cr’s , so each Cr will have
a charge of +3
o Cr has a charge of 3+ →Chromium(III)
= Chromium (III) Sulfide
Naming Rule 3: When polyatomic ions are involved, follow Rules 1 & 2. Write full polyatomic name in
place of cation or anion.
Examples:
1) K2SO4
o Look at K first! ← K is in group 1 (only can have a charge of 1+)
o Need to recognize SO4 as sulfate
= Potassium Sulfate
8
2) CuCO3
o Look at Cu first! ← Cu is a transition metal (can have a charge of 1+ or 2+)
o To determine charge of Cu → look at CO3
o You need to recognize CO3 as carbonate
o CO3 has a charge of 2o There is one CO32- → overall negative charge of -2
o To balance a negative two, you must have a positive two
o So, the overall charge of Cu is +2
o Cu has a charge of 2+ → Copper(II)
= Copper (II) Carbonate
Writing Rule 1:
1) Write the formulas for the cation and anion, including charges
2) Check to see if the charges are balanced
o If balanced, just remove charges
o If not balanced, continue with rule #3
3) Balance charges
o Use parentheses if more than one polyatomic in is needed
o Write subscripts if more than one ion is needed to balance
o Use crisscross method to balance subscripts
o Remove charges
Example:
1) Barium nitrate
 Write the formulas: Ba2+ NO31 Think: Do +2 and -1 balance each other? NO!….
 Ba2+ NO31- → Ba(NO3)2
NOTES: Naming Molecular Compounds
A molecular compound is formed between a two nonmetals. Also known as a covalent
compound.
How do I know it
is a molecular
compound?
Rule: For the 1st nonmetal:
o Name the element
o Use the prefix if there is more than one of
that element
For the 2nd nonmetal:
o Name the element
o Always include the prefix
o Use –ide ending
Example: NF3
o Two nonmetals! = covalent
o First element:
o Nitrogen → only one = no prefix
o Second element:
o Fluorine = fluoride
o 3 of them = prefix “tri-“
= nitrogen trifluoride



NOTES: Naming & Writing Acids
A form of ionic compound
Hydrogen salt dissolved in water (aq)
Binary: contains two elements
o Hydrogen + nonmetal
Oxyacid: contains oxygen
o Hydrogen + polyatomic
Naming & Writing Use prefix “ hydro” – root of nonmetal -- ic acid
Binary Acids:
Example #1: HCl
 Hydro – Chlor- ic Acid → Hydrochloric Acid
Example #2: Hydrofluoric Acid
 HF
Naming & Use root of anion (polyatomic) then check ending
Writing Oxyacids
 Polyatomic ends in –ate
Root –ic acid
 Polyatomic ends in –ite
Root –ous acid
Example #1: HNO3
 HNO3 →Nitrate→ ends in -ate→ root-ic
→Nitric Acid
Example #2: HNO2
 HNO2 →Nitrite→ ends in -ite→ root-ous
→Nitrous Acid
Example #3: Sulfuric Acid
 Sulfuric → ends in –ic → polyatomic must end in –ate → sulfate
 Two H+ must balance -2 charge on sulfate ion, SO42→H2SO4
