What is an ion?
An atom with a charge (positive or negative)
100
Which molecules are more polar? NH or OH 
OH because of greater electronegativity difference 
100
What do resonance structures show?
Bonding in molecules or ions that cannot be correctly represented by a single Lewis structure, instead it has multiple correct way of drawing it.

Dipole-Dipole and LDF
100
What is the molecular shape of H2O 
Bent
200
What is the name of ionic compounds? 



Crystal Lattice
200
Which direction does the dipole point to in a bond? 
To the atom with the greater electronegativity
200

Do ionic bonds have High/Low melting point? Does it dissolve? 

High melting point

Yes, it dissolves 

200
Is the molecule CCl4 polar or nonpolar? What is the molecule's geometry?

What bond type conducts electricity?
Ionic
300
What type(s) of elements make up an ionic bond? (e.g. metals, nonmetals, and metalliods)
A metal and a nonmetal
300
What symbol(s) are used to represent the opposite ends of a dipole? 

A bond where one side is slightly positive and one side is slightly negative, represented with lowercase delta + or -

300
Draw the complete Lewis structure for sulfur dioxide, SO2. 
sulfur is central, resonance with one double bond
300
List the name of molecular shapes that are nonpolar if all the outer atoms are the same. 
Linear and Tetrahedral 
300
Is CO2 a polar or nonpolar molecule? Explain your answer
Non-polar molecule, because of the geometry, the dipoles cancel each other out resulting in a non polar molecul
400
What is the difference between a cation and an anion?
A cation is positive and an anion is negative.
400
What type of bond would boron and fluorine form? Polar or non polar? 
A polar covalent bond
400
What is the Lewis structure for SeH2, and the molecular shape? 
Se with single bonds, bent
