Bonds
Different types of bonding
What are Covalent, Ionic, Metallic?
What the dots represent in a Lewis Dot Structure
What are valence electrons?
The three types of polarity
What is nonpolar covalent, polar covalent or ionic?
Avogadro's number & reasoning for the Mole
6.02 x 1023 & in order to "count" extremely large quantities
The amount of hydrogen atoms in sucrose
What is 22?
The type of bond where electrons are shared between nonmetal atoms (may not dissolve in water, don't conduct electricity, etc.)
What is a Covalent bond?
The amount of valence electrons Silicon has if it is in Group 14 and has 14 protons
What is 4 valence electrons?
The type of polarity where ΔEN < 0.4, 0.4 ≤ ΔEN < 1.7 or ΔEN ≥ 1.7
What is nonpolar covalent, polar covalent and ionic?
What to do with Avogadro's number when converting particles to moles and then moles to particles
What is divide and then multiply?
The direction you draw dots around an element on a lewis dot structure
What is one at a time, counterclockwise?
The type of bond where electrons are transferred from a non-metal atom to a metal ion (leading to significant changes in charges)
What is an Ionic bond?
A chemical rule of thumb that reflects the theory that elements tend to bond so that each atom has eight electrons in its valence shell, giving it the same electronic configuration as a noble gas
What is the octet rule?
The direction of a bipole for H2O
What is towards Oxygen?
The amount of moles in a sample of H₂SO₄ when we know there are 4.89 x 1025 atoms of oxygen
The names of common molecular shapes (think CO2, H20, NH3, BF3 and CH4)
What is linear, bent, trigonal pyramidal, trigonal planar and tetrahedral?
The type of bond that is present in H2O, N2 & CO2
What is covalent bond?
The bonds that are created between the carbon and oxygen atoms in CO2 (how about between nitrogen atoms in N2)
What are double bonds? (What are triple bonds?)
The slight charges (one + and one -) created in Hydrogen Chloride
What is H slightly positive and Cl slightly negative?
The number of moles in 2.81 g of copper (II) hydroxide, Cu(OH)₂
What is Cu = 63.55 g/mol, O = 16.00 g/mol (×2) and H = 1.008 g/mol (×2) to get the molar mass of 97.566g/mol, then do 2.81g/97.566g/mol to get 0.0288 moles?
The bond angle amounts for CO2 (linear), H2O (bent) and NH3 (trigonal pyramidal), BF3 (trigonal planar) and CH4 (tetrahedral)
What is 180°, 104.5°, 107°, 120° and 109.5°?

The name of the shape of CH4 and its polarity/electronegativity
What is tetrahedral and .35 nonpolar
The amount of molecules in 20.0 g of chlorine gas (Cl2)
What is 20g / 70.0 g/mol x 6.02 x 1023 = 1.7 x 1023?
