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)
What types of atoms are included in most molecules?
Two nonmetals
What are polyatomic ions?
ions containing more than one element
How do we name covalent molecules?
We use prefixes indicating how many of each atom are in a molecule.
What does VSEPR stand for?
Valence Shell Electron Pair Repulsion Theory
What happens with the electrons in an ionic compound?
the electrons are donated from one atom to another
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
Coordinate: the shared pair of electrons comes from one (the same) bonding atom
What groups on the periodic table are cations? anions?
Cations: groups 1, 2, and 13
Anions: 15, 16, and 17
What is the difference between polar and non-polar covalent molecules?
Polar: unequal sharing of electrons
non-polar: equal sharing of electrons
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.
When are roman numerals used in naming ionic compounds?
when the cation is neutral or does not have a fixed charge/is a transition metal.
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 barium reacting with arsenic
Barium Arsenide
Br3As2
Give the formula for the molecule Sulfur Hexafluoride.
SF4
Name the orientations:
Linear Triatomic
Square Planar
T-shaped
What should the total charge be on an ionic compound
Neutral
What are 4 exceptions to the octet rule when covalent bonding? What are their exceptions
H can only form one bond consisting of 2 electrons due to its small size (it only has a 1s level)
Br, P, S can hold more than 8 electrons (10-12) in their valence shell.
Give the name and formula for gallium reacting with acetate
Gallium Acetate
Ga(CH3COO)3
Name the following N3F7
Trinitrogen Heptaflouride
Name the following orientations:
Trigonal Planar
Bent
Trigonal Pyramidal
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
What are resonance structures?
Resonance structures are structures that occur when it is possible to draw two or more valid electron dot structures that have the same number of electron pairs

Iron (III) Hydrogen Phosphate
Fe2(HPO4)3
Is chloroform (CHCl3) polar or nonpolar?
Polar
Name the following orientations:
Tetrahedral
