1. Warm-up: 10/12---Thursday
When the bell rings… Be quiet and ready for class. Read the new objectives and essential questions. Make sure your word wall example is pass up to the front of your row, you have a pen/pencil, and the notes.

2. Reminders for today… Sign out a computer and log on
Before you start anything make a plan for what you are going to accomplish today…
Go to my website and use the websites provided (first period you may use other sources in order to complete your project.
Remember to cite your sources and be sure to consider quality and neatness when creating your products.

3. Warm-up from Bill Nye video…
What is an atom?
What are the three main parts of an atom.
How do the particles of an atom differ in electrical charge?

4. An atom is the smallest particle an element can be divided into and still be that element. The 3 parts are proton (positive charge+). Neutron (no charge 0), and electron (negative charge -)

5. Warm-up
List how many protons and electrons the following elements have: Hydrogen, Sodium, Iron, and Krypton

6. In what ways are atoms of Oxygen different than atoms of Carbon?
Warm-up
In what ways are atoms of Oxygen different than atoms of Carbon?
Take the candy atoms sheet off of front table and read it.

7. Warm-up
Take a periodic table from the front table, choose 3 colored pencils and create a color coded key for solids, liquids (only 2 on the table), and gases.

8. Draw the atomic structure of an element from the periodic table.
Warm-up
Draw the atomic structure of an element from the periodic table.
Label the nucleus, protons, neutrons, electrons and charges.

9. Construct an analogy: Element:Compound as _____: _____
Warm-up
Construct an analogy:
Element:Compound as _____: _____
Atom:Element as ________: _______
Take the candy atom instructions from the front table.
On the back of your sheet draw the atomic structure of an
atom of your choice with an atomic # between 2-10.
I must approve your drawing before you can get materials
to build your 3-D model.

10. The Atom and the periodic table

11. Objectives Describe and define atoms.
Recognize that all matter is made up of atoms and atoms of the same element are all alike, but are different from the atoms of other elements.
Describe the relationship between numbers of protons and atomic number on the periodic table.

12. What is the relationship between atoms and elements?
ESSENTIAL QUESTIONs

How are atoms of one element similar to and different from atoms of other elements?

13. What is the relationship between atoms and elements?
Warm-up
Can you answer the essential questions…
What is the relationship between atoms and elements?
How are atoms of one element similar to and different from atoms of other elements?

14. What is a pure substance? Is a substance in which there is a
uniform composition
of “particles”. The
particles we are
talking about are
atoms.
What is a pure
substance?

17. A substance that contains only one type of atom
A substance that contains only one type of atom. All known elements are organized on the periodic table of elements.
What is an
element?
meet the
elements
song

18. What is a
compound?
Is a combination of elements that come together through a chemical reaction and becomes something called a molecule.
A molecule is two or more different elements combined in a specific ratio.

19. The smallest part of an element that has the same properties of that element. In Greek, means “uncuttable”.
What is an atom?

22. What is an atom? Atom cont…
These particles are too small to be seen with a microscope.
Atoms have all the properties of matter: mass and volume

23. Superman Study Jams atoms

25. + What Is an atom Protons – Made

26. What 2 things are found inside the nucleus?
What Is
an atom
Made
of?
Neutrons –
Found in the atom’s nucleus
and has no charge. The
nucleus contains most of the
atom’s mass n
Neutrons
What 2 things are found inside the nucleus?
Neutrons

27. - What Is an atom Made of? Electrons –
Found circling the atom’s nucleus.
- Each has a negative charge.
Electron
Electrons

28. Label Me! 1. 3. 2. 4.

29. What is the atomic number? The atomic number is the number of
protons in the
nucleus of that
atom. All atoms of
the same element have the same atomic number.
What is the
atomic
number?

30. Here is an example of one of the elements on the periodic table.
atomic number - # of protons in the nucleus. 3 Li
Lithium
6.94
element symbol
element name
atomic mass –mass of the protons and neutrons

31. What is the Atomic Number?

32. Mass #
Isotopes

34. How do Atoms of Different Elements Differ?
Starting Simply The hydrogen atom has one proton and one electron.
Now for Some Neutrons The helium atom has two protons, two neutrons, and two electrons.
Building Bigger Atoms For bigger atoms, simply add protons, neutrons, and electrons.
Protons and Atomic Number The number of protons in the nucleus of an atom is the atomic number of that atom. All atoms of an element have the same atomic number.
