Ionic
What is the difference in EN between O ( 3.5 ) and H ( 2.1)
END=1.4
Name SO3
Sulfite
Identify the VSEPR shape of methane (CH₄).
Tetrahedral
What type of bond occurs when electrons are shared equally?
Covalent
Fr = lowest
F= highest
What is the correct formula for aluminum oxide?
Al2O3
How many lone pairs are on the central atom in NH3
zero
Which type of bond hold Cu atoms together in a wire?
Metallic bond
Polar Covalent
Write the Formula for calcium nitrate
Ca(NO3)2
Draw the lewis Structure for CO2
Look at board
Define and give an example of an ionic, covalent, and metallic bond
What is H2O polar while CO2 is considered Nonpolar
Hydrogen and Oxygen have a higher END it is between 0.3 and 1.7 which falls in the realm of Polar covalent. Carbon and Oxygen have a small END that falls below 0.3 which makes it nonpolar covalent. The electrons are shared more evenly between carbon and Oxygen then between Hydrogen and Oxygen.
Write the names for: CuSO4, HNO3, and PCl5
Copper(II) sulfate, Nitric Acid, and Phosphorus pentachloride
Compare single, double, and triple bonds in terms of bond strength.
Explain why NaCl is ionic, not covalent, even though both atoms achieve full out shells
They are not sharing electrons to achieve outer shells, like in covalent. The Na atom is giving its only valence electron to chlorine; this gives chlorine 8 valence electrons. ( a full outer shell) and Na now has zero outer electrons but the shell underneath is complete and full. So they are both balanced and stable.
Give an Example of a Diatomic compound, Then Identify and explain the type of bond between the atoms
Any compound that has two of the same elements ex. H2, O2, He2 The bond would be Nonpolar Covalent, because if you subtracted the Electronegativity it would be 0, if they have the same electronegativity then they will be sharing the electrons equally.
Step by Step, explain how to name a compound with a transition metal (give formula + name).
Step 1: Name the Cation (metal) and place it first
Step 2: Name the anion (nonmetal or polyatomic).
- if it's a nonmetal, then you drop the ending and add -ide, if its a polyatomic you just right its name
Step 3: Identify the charges (oxidation state) of both the anion and the cation.Change to the subscripts accordingly
Step 4: Place a Roman numeral of the oxidation state after the transition metal.
Draw the Lewis structure for SO3 and Identify the molecular shape.
Shape is trigonal planar.
