Slide4Atoms
Notes
Tennessee SPI Objective:
Recognize that all matter consists of atoms.
Science
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
Bowling Ball
(solid)
Orange Juice
(liquid)
The Sun
(plasma)
Oxygen
(gas)
These objects are made of matter. Therefore they are made of atoms.

Science
Rock

Flower
What do these 3 items have in common?
They all have mass and take up space
(volume
)
They are comprised of or contain solids, liquids, or gases
So they are all made of matter which is made of atoms
Slide6Things that are not made of matter
Ask yourself if it is a solid, liquid, or gas
Example
:
Force is not made of atoms
Example
:
Energy 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.
Example
:
Time is not made of atoms
Time
Solar Radiation
Magnetic Force
Energy is not a solid
Energy is not a liquid
Energy is not a gas
Force is not a solid
Force is not a liquid
Force is not a gas
Slide7Atoms 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)

Slide9Electrons are located in the electron cloud in areas called electron shells
This atom has 2 electron shells.

These can also be called
electron energy levels
or
electron orbitals

Borh
models analyze the structure and reactivity of an atom.Rules:Put the appropriate number of protons and neutrons in the nucleus.Fill energy levels with atoms. Remember to fill the prior level before moving to the next level.1st Energy Level- 2 Electrons2nd Energy Level- 8 Electrons3rd Energy Level- 8 ElectronsTry the following Bohr models with your teacher:H (Hydrogen)
C (Carbon)
Na (Sodium)
Ne (Neon)
