Final proficiency review

P=9 N=10 E=9

  • How many protons, neutrons, and electrons does fluorine have?

  • Draw and label an atomic model of the element. (protons/charge, neutrons/charge, electrons/charge, nucleus, and electron cloud)

  • What is the charge of the nucleus of the atom?

  • What is the charge of the entire atom?

  • How many valence electrons does it have?

  • If this element bonded with lithium and gained an electron what type of ion would it become?

Group Number

  • How do we know the number of valence electrons by looking at the periodic table?

  • How many valence electrons does oxygen have?

  • If two oxygen atoms formed a bond what kind of bond would form? How do they bond? How would you know?

  • Show the bond the forms between two oxygen atoms.

  • You take a hot shower in the morning, and there are droplets on the outside of the shower door. What two phase changes can you infer have happened?

Vaporizing – Steam from hot shower

Condensation – Steam cools down and forms droplets

You combine paper clips, water, sugar, and marbles in a bowl.

  • This is an example of two or more substances that are physically blended but are not chemically bonded, therefore this is a _____________________.

  • How could you separate the parts of this mixture?

  • Is this a heterogeneous mixture or homogeneous mixture or both? How do you know? Give specific examples from the scenario.

MIXTURE

Filtration – sugar and water from paperclips and marbles

Magnetism – Paperclips from Marbles

Distillation or Evaporation – Sugar and water

Both – HOMOGENOUS (sugar and water)

It is evenly mixed together

HETEROGENEOUS – water, paperclips, and marbles

Not evenly mixed together
