Tennessee SPI Objective:
Recognize that all matter consists of atoms.
Essential Learning
Students will examine the basic structure of atoms
and will learn to distinguish between things that
are comprised of atoms and those that are not.
Essential Question(s)
What is the basic structure of atoms, and how can
we distinguish between things made of atoms and
things that are not?

Tennessee SPI Objective:
Recognize that all matter consists of atoms.
All matter is made up of atoms
Matter is anything that has mass & takes up space (volume)
Matter is anything that is solid, liquid, gas, or plasma
These objects are made of matter. Therefore they are made of atoms.

Orange Juice
(liquid)
Oxygen
(gas)
The Sun
(plasma)

Tennessee SPI Objective:
Recognize that all matter consists of atoms.
What do these 3 items have in common?
They all have mass and take up space (volume)
They are either solid, liquid, or gas
So they are all made of matter which is made of atoms
Rock
Insect
Flower

4. Things that are not made of matter
Ask yourself if it is a solid, liquid, or gas
Time
Example: Time is not made of atoms
Time is not a solid: You can not touch it
Time is not a liquid: You can not drink it.
Time is not a gas: You can not smell it.
Solar Radiation
Example: Energy is not made of atoms
Energy is not a solid
Energy is not a liquid
Energy is not a gas
Magnetic Force
Example: Force is not made of atoms
Force is not a solid
Force is not a liquid
Force is not a gas

5. Be 4 Legend 9.0 Notes Science SPI 0807.9.1 Atoms
We once thought atoms were the smallest particles.
We now know there are even smaller particles
They are called sub-atomic particles
(protons, neutrons, and electrons)
Notice the sub-atomic particles in this beryllium atom
It has 4 (blue) protons (So the atomic number is four)
It also has 5 (green) neutrons and 4 (orange) electrons 4 Be

6. Li 3 6.9 Notes Science SPI 0807.9.1 Atoms
Atoms are made of three sub-atomic particles…
…3 protons (the blue circles) (atomic number is 3)
…4 neutrons (the green circles)
…3 electrons (the orange circles) 3 Li
Lithium
6.9
Here is a model of
a lithium atom

7. Legend Notes Science SPI 0807.9.1 Atoms
Protons: positive charge, found in the nucleus of atoms
Note: In atoms the number of protons & electrons are the same
Neutrons: no charge, also found in the nucleus of atoms

8. Legend Notes Science SPI 0807.9.1 Atoms
Electrons are located in the electron cloud in areas called electron shells
This atom has 2 electron shells.
(see cloud in green area below)
These can also be called electron energy levels or electron orbitals.
The green area is the electron cloud area
