                Atomic Mass
   The nucleus contains most of the mass
    of an atom
    – Because Protons and Neutrons are much
      larger than electrons
   The electron cloud accounts for most
    of the volume of the atom.

              How do atoms become electrically charged?


                          Charges
   If something gains electrons -

   Static electricity - accumulation
    of excess charge on an object

  arrangement of
  electrons effect
  the properties of

How does the arrangement of electrons effect the properties of
                        an atom?

                  Electron Placement
   Electron placement is
    responsible for chemical
    properties. Especially the
    number of outer or valence
    electrons.
   Electrons always fill the inner            QuickTime™ and a
    “shells” before the outer.      TIFF (Uncompressed) decompressor

   The first “shell” or energy
    level is full with 2 electrons.
   2nd- 8 3rd- 18 4th- 32
   Not every atom follows that
    exact pattern.
How does the arrangement of electrons effect the properties of
                        an atom?

                 Energy Levels
   The electrons in an atom are located in
    energy levels around the nucleus.

   The outer energy
    level is called the
    valence shell.

    hold a different
    number of electrons.
    – Energy level one can
      hold up to 2 electrons.
    – Energy level two can
      hold up to 8 electrons.
   The electrons will try
    to stay far away from
    each other.
How does the arrangement of electrons effect the properties of
                        an atom?

1.   Isotopes are atoms of the same element that differ
     only in the number of neutrons.
2.   The isotope boron-10 has one less neutron than the
     isotope boron-11.
3.   The average atomic mass of an element is the
     average mass of the mixture of its isotopes.
4.   The two chlorine isotopes have the same number of
     protons and the same number and arrangement of
     electrons. However, chlorine-37 has two more
     neutrons than chlorine-35.
5.   Because they occur in equal parts, the average

 What does the periodic table tell us about
                 elements?
How do you determine the number of
 protons, neutrons, and electrons?
Well….it’s kind of like this…
1.  The protons is equal to the atomic number.
2.  Normally, the electrons are equal to the
    protons, unless it has a charge.
    Why do I say “normally”?
3.  The neutrons plus the protons equals the
    mass number, so……mass number -
    protons = neutrons
Now that wasn’t so bad.

  Elements & Periodic Table
EQ: How would you recognize
 an atom if you saw one?

Bellringer:
Mystery
Envelopes!
                           EQ?


          Properties of Atoms
A. Elements are abbreviated in scientific shorthand

-first letter or two of the element’s name
     Ex:
         Carbon = C
         Aluminum = Al
         Silicon = Si
         Iron = Fe
                                EQ?

B. Atom – smallest piece of matter that still has properties of the
   element
   Parts of an atom:
   1. Protons – have electrical charge of 1+
  2. Neutrons – do not have and electrical
     charge
  3. Electrons – have and electrical charge
     of 1-
                    EQ?


Where are they located?

- Protons and
  neutrons are in
  the nucleus of
  the atom
  - Electrons
  surround the
  nucleus
                      EQ?


                   Quarks
C. Protons and neutrons
 are made up of smaller
 particles called quarks.
 1. Six quarks are known
 to exist
     - the sixth is called
 the top quark
EQ?
                                   EQ?
D. Scientists use scaled-up models to represent atoms.

             Atomic Mass
   The nucleus contains most of the mass
    of an atom
    – Because Protons and Neutrons are much
      larger than electrons
   The electron cloud accounts for most
    of the volume of the atom.
                      EQ?


               Atomic Mass
     The unit of measurement for an atom is
      the amu (atomic mass unit)


The mass of
protons &
neutrons is
almost 2
amu
                    EQ?


    How do I find the protons?
   Elements are different because they
    have different #’s of protons.
          Atomic Number = # of protons

How many protons in these examples?
 Oxygen -
 Carbon -
 Sn -
                      EQ?


      How do I find the electrons?
     The number of electrons usually is the
      same as the number of protons.

If the atom as a
whole has a
positive or negative
charge (ion), then it
will have different
numbers of
electrons.
                      EQ?


     How do I find the neutrons?
Atomic Mass # - # protons + # neutrons

So…
# Neutrons = Atomic Mass # - Atomic #
             (p + n) - (p)
                 EQ?


 How do I find the neutrons?
How many neutrons are in:
 Lithium
 Sulfur
 K

           Outer electrons
   The number of
    electrons in the
    outer energy level
    will determine
    what that atom can
    bond to or its
    reactivity.

                     Isotopes
   Atoms can have different properties if they have
    different #’s of neutrons
    – These are called ISOTOPES

    Ex:
    *Normal Hydrogen
    has 1 neutron
    *Hydrogen isotopes
    can have 0 or 2
    neutrons
                    EQ?

             Radioactive dating
   Atom decay can be used to
    find the ages of bones.
   Half-life: The time it takes
    for 1/2 of the element to
    change into another
    element
   A common radioactive
    element used is Carbon-14,
    which has a T1/2 of 5,715
    years.
                     EQ?


    Radioactive Dating Practice
How old is the fossil?

   50% left with T1/2 of 25 yrs =
   25% left with T1/2 of 100 yrs =
   75% left with T1/2 of 10 yrs =
   12.5% left with T1/2 of 6 yrs =
                       EQ?


            Naming Isotopes
   Use the element + the atomic mass
    – C-14 has a mass of 14
    – C-12 has a mass of 12

    *The mass listed on your periodic table is
      the average atomic mass.
    *This number is closer to the mass of the
      isotope that is most common.
                             EQ?

       Finding the Average Atomic
                  Mass
Fraction of   x mass +   Fraction of   x mass = Average

Ex: 10 out of 12 samples of an element have a mass of 12
and 2 out of 12 samples have a mass of 14. What is the
aam?

          10/12 x 12 + 2/12 x 14 = 12.3 amu’s
   **Since the aam is closer to “12,” you can tell that
   the 12 isotope is more common.
