Title: Chemical Bonding


1
Chemical Bonding
  • Why bond anyway?
  • Increase Stability
  • Decrease Potential Energy stored energy is
    difficult to maintain (batteries expire, food
    spoils).
  • What is a bond?
  • an attractive force between atoms or ions that
    binds them together as a unit.

2
Chemical Bonding
  • Determining Bond Type
  • There are two main bond types ionic and
    covalent.
  • Ionic bonds can be identified because...
  • The first element is a metal (cation)
  • The second element is a nonmetal (anion)
  • The formula may include a polyatomic ion look
    for formulae that start with a metal and have 3
    or more elements.
  • Covalent bonds can be identified because...
  • The first element is a nonmetal
  • So is the second element these formulae are
    composed of nonmetals exclusively.

Ionic Formulae
  • Formula Structure
  • Elements present
  • Subscripts (shows how much of each element)

NaNO3
This is sodium nitrate.
If no subscript is present it means that there
is only one atom of that element
This is a formula unit of an ionic compound.
6
Ionic Nomenclature
  • Naming Rules
  • Write the names of both ions, cation first.
  • Change the ending of monatomic anions to -ide.
  • Polyatomic ions have special names that are not
    to be altered.
  • Stock System Use Roman numerals to show the
    charge of a cation if more than one is possible.
  • The overall charge must equal zero.
  • Example Fe(NO3)2 becomes

iron (II) nitrate
iron
(II)
nitrate
NO3- NO3- ? 2- charge Fex must therefore have
a 2 charge
7
Ionic NomenclatureThe Criss-Cross Method
  • This is the fastest way to determine an ionic
    formula. This requires some rough drafting.
  • Step 1 Write the Ions out (cation on the left,
    anion on the right)
  • Step 2 Paying no attention to the charge
    criss-cross the numbers appearing with each ion
    to the other ion so that they become a subscript.
  • Step 3 Reduce/Simplify these numbers so they are
    the simplest whole number ratio.
  • Example

cation on the left
anion on the right

Step 3, not necessary for this compound.

Ionic Nomenclature Practice
  • Puzzle pieces Cations Anions
  • Take the 14 cations and 13 anions provided.
  • Come up with as many chemical combinations as
    you can (there are 182 possibilities).
  • You may use the Criss-Cross method rather than
    the puzzle pieces.
  • Write the chemical formula and name of each.
  • Follow the naming rules and ONLY use one cation
    and one anion type at a time.
  • Example

Al3 aluminum
AlNO22 Aluminum nitrite
Al(NO2)21 Aluminum nitrite
Al(NO2)3 Aluminum nitrite

Ionic Nomenclature
  • Getting a formula out of a name
  • Write the symbol of both ions, cation first.
  • Include known charges of the ions.
  • Roman numerals in the Stock system tell the
    charge of cations with multiple oxidation states.
  • Polyatomic ions dont have more than one
    oxidation state.
  • Paying no attention to the signs of the charges
    crisscross them as subscripts for the opposite
    ions.
  • Use parentheses if there is more than one of a
    polyatomic ion type.
  • Example iron (II) nitrate becomes

Fe NO3
Fe NO3 2
