Chapter 4 Lesson 1
Today You Need:
4.1 Notes handout (glued in on the right side!)
Pencil or pen
3 colored pencils, pens, or highlighters
What is Matter?
Anything that has MASS and takes up SPACE
Examples of matter?
The smallest unit of matter is the ATOM
Right Side
“Atom”
From the Greek word atoma, meaning “INDIVISIBLE”.
Right Side
Think – Write -From the Greek word atoma, meaning “indivisible”.
Using this definition, predict why the atom was called the atom.
{Complete Sentences!}
Left Side
My Prediction:
Pair – Write
Share with your partner.
Write down their thoughts in a new color.
Left Side
My Prediction: My Partner’s Prediction:
“Atom”From the Greek word atoma, meaning “indivisible”.
Greek Philosopher Democritus could believed that you could only cut matter up a certain amount of times before it was too small to be divided.
Right Side
Parts of the Atom
All Atoms are mostly EMPTY SPACE surrounding a tiny NUCLEUS.
“subatomic particles” – particles that are SMALLER than an atom
There are 3 main subatomic particles.
Protons, Neutrons, Electrons
Right Side
Protons
Use your first color to highlight or shade behind the word “Protons” on your handout.
Symbol: P+
Charge: + 1
Mass ~ 1 amu
Right Side
Units
What units do we use for measuring distance?
What units do we use for measuring mass?
Left Side
Units
What units do we use for measuring distance?
Inches, centimeters, miles, kilometers, yards…
What units do we use for measuring mass?
Pounds, ounces, gramsamu: ATOMIC MASS UNIT = for measuring mass
Left Side
Right Side
Neutrons
Use your 2nd color to highlight or shade behind the word “Neutrons” on your handout.
Symbol: N
Charge: 0 (Neutrons are Neutral)
Mass ~ 1 amu
Right Side
Electrons
Use your 3rd color to highlight or shade behind the word “Electrons” on your handout.
Symbol: e-
Charge: - 1
Mass ~ 0 amu
Right Side
AMU repeat
What is amu?Atomic mass unitUse to measure mass of subatomic particles.
Right Side
Create a Chart
Create a chart that shows the symbol, charge, and mass (amu)
Left Side
Create a Chart
Create a chart that shows the symbol, charge, and mass (amu)
Left Side
Particle Symbol Charge Mass (amu)
proton P+ + 1 1
neutron N 0 1
electron e- - 1 0
Lithium Atom:3P+, 4N, 3 e-
Use your 3 colors:1 color for Protons, P+2nd color for Neutrons, N3rd color for electrons, e-
Right Side
Draw a new atom
Draw Berylium, Be
Be has 4 protons, 4 electrons, and 5 neutrons.
Don’t forget to color-code the subatomic particles.
