Review Key Concepts
• Number your lab book to 26. Skip 1 line between
numbers.
• Only 2 people can be at the same station at a
time. If there are already 2 people at a station,
move on to a different station.
• You do not need to go in order.
• Just write your answer in your lab book.
• You may check your answers at the answer
station.
• If you are not working well, you will complete
the stations at your table.
Tuesday Oct 16 or Wednesday Oct 17
Do Now:

2. How do you think an atom of gold is different
from an atom of silver?

Quiz
• No talking while quizzes are out.
• You may use any notes you have to answer the
questions.
• Place your quiz upside down when you are
finished. You may draw on the back while you
wait for your classmates.
The Periodic Table of the Elements
• The periodic table shows all the atoms that
everything in the known universe is made from.
• Each box contains information about a different
atom.
• It’s kind of like the alphabet in which only 26
letters, in different combinations, make up many
thousands of words. The atoms of the periodic
table, in different combinations, make up millions
of different substances.
Joke
A song that lists all the elements…
• http://www.privatehand.com/flash/elements.
html
While you listen, make tally marks to keep track
of the elements you’ve heard of. It’ll go fast, so
try to keep up.
This song mentions elements and
compounds

bM
• Write down at least 2 things you learned or 2
things that surprised you from this song.
Things to know about atoms…
Things to know about atoms…
• In every atom there are equal amounts of
protons and neutrons.
• Example: Sodium has 11 protons so it has 11
electrons.
• Example: Silver has 47 protons so it has 47
electrons.
Things to know about atoms…
• The atomic number of an atom tells you how
many protons are in the atom.
• Example: Oxygen has an atomic number of 8,
so it has 8 protons. (And since it has 8
protons, how many electrons does it have?)
Atomic Mass
• The atomic mass of an element is based on
the mass of the protons, neutrons, and
electrons of the atoms of that element. The
mass of the proton and neutron are about the
same, but the mass of the electron is much
smaller (about 1/2000 the mass of the proton
or neutron). The majority of the atomic mass
is contributed by the protons and neutrons.
Things to know about atoms…
• Atomic mass is how much mass the atom has.
• Most of the mass of an atom comes from the
protons and neutrons.
• Electrons are so small that only a tiny fraction
of the atomic mass comes from them.
Things to know about atoms…
• How do you know how many neutrons an
atom has?
• Subtract the atomic number from the atomic
mass to find how many neutrons are in an
atom.
• Example: Lithium has an atomic number of 3
and an atomic mass of 7. 7-3=4. There are 4
neutrons.
The periodic table tells you everything you
need to know about each type of atom.
