Snapshot
• __(1)___ is anything that has mass and takes up space.
• All matter is made up of ___(2)__.
• Convert the following
• .56 L= _(3)_ mL
• 34.8 dm = _(4)__ dam
• __(5)__ are created by combining an acid and a base.
Snapshot
• Which is larger a dkl or a dl?
• Convert the following into scientific notation
• 34508
• 89.43
• .000621
• List the steps of the scientific method in order?

### PS.3 The Atom Model

The student will investigate and understand the modern and historical models of the atomic structure.

Parts of an Atom
• Subatomic particles
• 3 types
• Protons
• Positively charged ( + )
• Set amount for each element
• Equals the atomic number
• Electrons
• Negatively charged ( - )
• Neutrons
• No charge = neutral ( 0 )

PS.3 Atomic Model: The student will understand the historical & modern model of the atomic structure

Locations within the Atom
• Nucleus
• Central part of an atom
• Where majority of mass is located
• Contains protons & neutrons
• Electron cloud
• Orbitals or shells
• Where electrons are located constantly moving

PS.3 Atomic Model: The student will understand the historical & modern model of the atomic structure

195 North (Powhite Parkway) Can hold 8 electrons

Sweet Frog CarytownContains protons & neutrons

Energy Street Can hold 2 electrons

Matterville

Interstate 95 N Can hold 18 electrons

3rd Verse:

Neutrons can be found,

Where protons hang around;

Electrons they surround

The Atoms Family.

Chorus

Chorus:

They are so small.

(Snap, snap)

They’re round like a ball.

(Snap, snap)

They make up the air.

They’re everywhere.

Can’t see them at all.

(Snap, snap)

1st Verse:

They’re tiny and they’re teeny,

Much smaller than a beany,

They never can be seeny,

The Atoms Family.

Chorus

2nd Verse:

Together they make gases,

And liquids like molasses,

And all the solid masses,

The Atoms Family

Chorus

Snapshot
• A smaller part of an atom is called a __(1)__.
• __(2)__ is the part of the atom where _(3)___ and neutrons are found.
• __(4)___ have a negative charge and are equal to the number of __(5)___ in a neutral atom.
• __(6)___ have no charge.
Model
• Scaled version of an original
• Used in studying the atom
• 5 Models
• Dalton
• Thomson
• Rutherford
• Bohr
• Electron-Cloud
Democritus & Dalton
• ~ 400 B.C.
• Greek philosopher
• Said all matter made up of small particles
• Named particles Atomos
• Un-cuttable
• He was unable to prove his idea
• John Dalton found proof in 1800’s
• Solid sphere

PS.3 Atomic Model: The student will understand the historical & modern model of the atomic structure

Thomson
• 1904
• Positive sphere with negative parts embedded
• Chips = electrons
• Cookie = 1 big proton

electrons

proton

PS.3 Atomic Model: The student will understand the historical & modern model of the atomic structure

Rutherford Model
• 1911
• Solid positive nucleus w/ majority of mass surrounded by electrons

PS.3 Atomic Model: The student will understand the historical & modern model of the atomic structure

Bohr Model
• 1913
• Electrons in fixed orbits around nucleus
• Nucleus made of positive protons & neutral neutrons

PS.3 Atomic Model: The student will understand the historical & modern model of the atomic structure

Electron Cloud
• Current Model
• Nucleus made up of protons & neutrons
• Electrons are not in fixed orbits
• Are frequently in certain areas
