10-8-12

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 17Do Now:1. What is the charge of a neutron? 2. How do you think an atom of gold is different from an atom of silver?

Periodic Table of the Elements

Whatever page you’re on

Watch Video

• Take notes while you watch. Anything you write down you will be allowed to use on the short quiz over the video content.

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

• http://www.youtube.com/watch?v=d0zION8xjbM

• 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.
