Word Wall Words- Quiz Friday!Add these in the
back of your SNB in the vocabulary section.

• 11. Mixture- combination of two or more
  substances that are not chemically combined.
• 12. Solution- a homogeneous mixture of two or
  more substances uniformly dispersed throughout a
  single phase.
• 13. Solute- in a solution, the substance that
  dissolves in the solvent
• 14. Solvent- in a solution, the substance in
  which the solute dissolves.
• 15. Suspension- a mixture in which particles of a
  material are more or less evenly dispersed
  throughout a liquid or gas.

45. Atoms Family

• 1st Verse
• Theyre tiny and theyre 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
• 3rd Verse
• Neutrons can be found,
• Where protons hang around
• Electrons they surround

Atoms Foldable- Inside

• Neutrons- Neutral particle NO charge (0)
• Inside the nucleus
• ½ of atoms mass
• Keeps protons together
• Neutrons Atomic mass- Atomic

Atoms- The smallest unit that an element can be
divided into and still be the same substance.
Isotopes- the same number of protons but have
different numbers of neutrons. (Isotopes are the
same as the Mass ) Atomic Mass Protons
Neutrons Atomic Number Protons Protons
Electrons

• Protons- Positively Charged ()
• Inside the nucleus
• The other ½ of atoms mass
• Protons Atomic
• (Elements Identity)

• Electrons- Negatively Charged (-)
• Outside the nucleus in the electron cloud
• No effect on atoms overall atomic mass.
• Responsible for ability to form bonds.

Make a connection!

• How Do Atoms of Different Elements Differ?

Discuss with your elbow partner!

Element Connection!

• For example
• The hydrogen atom has 1 proton and 1 electron.
• The helium atom has 2 protons, 2 neutrons, and 2
  electrons.
• For bigger atoms, simply add protons, neutrons,
  and electrons.

• Your task
• 1. Use the Periodic Table to
• arrange the Skittles on your
• coffee filter for the number of
• protons, neutrons, and electrons.
• 2. Use the BLUE cup to show that
• your group is finished and let me
• check.
• 3. Once your group has been
• checked, draw each in your SNB.
• 4. DO NOT EAT the candy until
• directed by me!

Exit Ticket

1. What are atoms? Where are they found?
2. Compare and contrast protons, neutrons, and
   electrons. Give examples.

Practice with Protons, Neutrons, Electrons, Mass
, Atomic

• Directions
• At your groups, you have a large Bohr Model.
• You will also have circles to represent
  protons(), neutrons(0), and electrons(-).
• Your group will use the information given about
  certain elements and show a model of each
  element.

• 1.Use the Element cards at your group and show
  the number of electrons, neutrons, and electrons
  for each element.
• 2. Use circles to represent the particles in the
  atom. (Use 3 different colors to represent the
  atom particles) Protons
• Neutrons
• Electrons
