What are ionic compounds made out of? (explain what any key term you use means)
a compound of atoms consisting of a cation (positively charged ion) and an anion (negatively charged ions)
100
What types of atoms are included in most molecules?
Two nonmetals
100
What are polyatomic ions?
ions containing more than one element with an overall charge
100
What is a Lewis dot diagram? (What does it show?)
Consists of a chemical symbol surrounded by one to eight dots representing valence electrons.
100
What does VSEPR stand for?
Valence Shell Electron Pair Repulsion Theory
200
What happens with the electrons in an ionic compound?
the electrons are donated (transferred) from one atom to another
200
What types of bonds can form during covalent bonding? (Explain what each one is)
Single: sharing of 1 pair of electrons
Double: sharing of 2 pairs of electrons
Triple: sharing of 3 pairs of electrons
200
What groups on the periodic table are cations? anions?
Cations: groups 1, 2, and 13
Anions: 15, 16, and 17

Draw a Lewis dot diagram of H2
H : H or H - H
200
What does Valence Shell Electron Pair Repulsion Theory tell?
That electrons will orient themselves as far away from each other as possible around the nucleus of an atom.
300
When are roman numerals used in naming ionic compounds?
when the cationdoes not have a fixed charge/is a transition metal.
300
What are atoms in a molecule trying to achieve when forming covalent bonds?
A full outer shell with 8 electrons.

Give the name and formula for Lithium reacting with Nitrogen
Lithium nitride
Li3N
300
Draw a lewis dot diagram of an atom of chlorine
Cl with 7 valence electrons
300
Name the orientations: 
Linear
400
What should the total charge be on an ionic compound
Neutral
400
What is one exception to the octet rule when bonding? What are their exceptions?
H can only form one bond consisting of 2 electrons due to its small size
400
Give the name and formula for gallium reacting with acetate
Gallium Acetate
Ga(CH3COO)3 or Ga(C2H3O2)3
400
What is the octet rule?
Atoms generally react by gaining, losing, or sharing electrons in order to achieve a complete octet of eight valence electrons.
400
Name the following orientation:
(Miss Mackey will draw on board)
Trigonal Planar
500
What is the difference between a lewis dot diagram and a lewis dot structure?
lewis dot diagrams show the separate valence electrons using dots
lewis dot structures show the bonds that form between atoms in a molecule with lines
500
What are polar covalent bonds? (What are they the result of?)
The unequal sharing of electrons in a covalent bond results in a polar covalent bond. The element with higher electronegativity value attracts the shared electrons more strongly, making that portion more negatively charged.
500
Give the name and formula for Fe+3 reacting with hydrogen phosphate
Iron (III) Hydrogen sulfate
Fe(HSO4)3
500
Draw a lewis dot diagram for CH3Cl
C is the central atom with 3 Hydrogen's around it and a Cl. The Cl would have 6 valence electrons on it.
500
Name the following orientations:
(Miss Mackey will draw on board)
Tetrahedral
