The AP test is coming up...you should ace this!

Test Your Knowledge On AP Chem!

Xenon has an atomic number of 54, so it has 54 protons!

54 Protons

Fluorine is the most electronegative. It's a trend you better know this!

Fluorine

Which element is the most electronegative on the periodic table?

Don't forget Coulomb's Law!! Potassium has a larger atomic radius than lithium, the attractions are weaker. Therefore, it takes less energy to remove an electron from the atom with weaker attractions. Lithium has a smaller atomic radius, with stronger attractions. Therefore, it takes more energy to remove an electron from an atom with stronger attractions.

Lithium has the higher ionization energy

Moles of solute/Liters of Solution

London Dispersion Forces are the weakest of the Intermolecular Forces!! Everything has them!

Hydrogen Bonds

Which Intermolecular  
force is the strongest?  


To the left

If the equilibrium constant is less than the Q value, which direction does the reaction shift?  


Endothermic Reactions have a positive change in enthalpy, and exothermic reactions have a negative change in enthalpy.

Only (aq) reactants and products are included in the equilibrium constant expression.

(aq)

What do you include in an equilibrium constant expression?  


LEO GER: Loss of electrons is oxidation and Gain of elections is reduction.

Oxidation reactions lose electrons.

You will see them as products first then reactants. If you see something that starts off as a reactant and ends as a product, that is a catalyst.

Intermediates are produced then used again.

BRU if you forgot this, why are you even taking this quiz.

Easy One:  
How many valence electrons does Hydrogen have?
