What do ionic bonds contain?
a metal and a non-metal
Which of these elements has 6 valence electrons?
Oxygen, Selenium, Sulfur
Look at the periodic table
What is a polyatomic ion?
Many atoms with a charge

Aluminum, Oxygen, Beryllium, Oxygen
Oxygen
Which of these liquids have high viscosity?
Milk, Molasses, Water, Methylene Chloride
Molasses
Which of the following is a polyatomic ion?
NH(4), N(3-), H(4), NH(4+)
NH(4+)
What physical property is used to separate the different fractions of petroleum?
Boiling Point
What is the name of the group that petroleum belongs to?
Hydrocarbons
A liquid that flows or moves very quickly and easily has what kind of viscosity?
Low viscosity
Small hydrocarbons have (what size) intermolecular forces between them?
Small
Be able to draw the electron dot diagrams for elements
See Mr. Krumpelman for help
Be able to complete a char for prefixes
Example: Hepta - - 7
Explain how a ionic bond “sticks” together?
They attract - - positive to negative
What are the differences between ionic and covalent bonds?
Covalent - - 2 nonmetals and they have shared electrons
Ionic - - metals + nonmetal and they transfer electrons
What is the difference between polyatomic cation and a polyatomic anion?
Cation = postive Anion = negative
How do you figure out how many valence electrons an atom has in the main group elements?
Main group number = number of valence electrons
Describe how fractional distillation works.
Must include heat, boiling point, vaporize
Be able to tell if a formula is ionic or covalent and then name it.
Example - - MgO - - Ionic - - Magnesium Oxide
OR
Di Hydrogen Monoxide - - Covalent - - H(2)O
Which element is a NON-reactive element?
Silicon, Neon, Nigrogen, Carbon
Neon
