ps 3 the atom model

PS.3 The Atom Model

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

parts of an atom
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
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

slide6

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

slide7

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

  • 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
Model
  • Scaled version of an original
    • Used in studying the atom
      • 5 Models
        • Dalton
        • Thomson
        • Rutherford
        • Bohr
        • Electron-Cloud
democritus dalton
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
Thomson
  • 1904
    • Positive sphere with negative parts embedded
    • Chocolate chip cookie model
      • 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
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
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
Electron Cloud
  • Current Model
    • Nucleus made up of protons & neutrons
    • Electrons are not in fixed orbits
      • Are frequently in certain areas
