1. What are the different levels of 1s < 2s < 2p < 3s < 3p < 4s < 3d < 4p < 5s < 4d < 5p < 6s
energy?
2. How do you convert Celsius to Fahrenheit = (Celsius x 9/5) + 32
Fahrenheit?
3. How do you convert Fahrenheit Celsius = (Fahrenheit - 32) x 5/9
to Celsius?
4. How do you convert Celsius to Kelvin = Celsius + 273.15
Kelvin?
5. How do you convert Kelvin to Cel- Celsius = Kelvin - 273.15
sius?
6. How do you convert Fahrenheit Kelvin = (Fahrenheit + 459.67) x 5/9
to Kelvin?
7. How do you convert Kelvin to Fahrenheit = (Kelvin x 9/5) - 459.67
Fahrenheit?
8. What is Hess's Law? When reactants are converted to products,
the enthalpy of the reaction is the same, no matter if it
occurs in one step, or a series of steps.
9. What is the Pauli Exclusion Princi- Each electron has a set of 4 numbers, called quantum num-
ple? bers (q.n.'s.) that specify it completely. No two electrons
in the same atom can have the same 4 q.n.'s. The primary
quantum number n tells you which of the main energy
levels you are in.
10. What is the principle of quantum Describes the distance of the orbital from the nucleus. The
number n? larger the value the larger the distance of the electron.

11. What is the magnetic quantum Tells us the 3D orientation of the orbital in space.
number ml?
12. What is the electron spin quan- Tells us the spin direction of the electron, +1/2 or -1/2
tum number ms?
13. What is the angular momentum This tells us the shape.
quantum number l?
14. Which areas of the periodic table Groups 1 & 2 & Helium = s
belong to which orbital?
Groups 3 through 12 = d
Groups 13 through 18 (not He) = p
15. What happens in terms of re- The reactions are more vigorous as we go down, like in
actions throughout the periodic Group 1.
table?
16. What are the reactive character- They are all very reactive because of their 7 valance elec-
istics of group 7 - halogens? trons. They have very high ionization energies & electron
affinities. Fluorine is very reactive and known as the tiger
of chemistry. The reactivity is the opposite as the rest. It
decreases as it goes down.
17. What kinds of atoms form to- Those who do not normally look to bond together from
gether in a hybrid state? number of valence electrons.
18. What is a hybrid state? Moving the composition of electrons throughout the s, p
and d levels of electrons.
19. What are the 3 different kinds of sp: 2 s --- 1s 1p
hybridization?
sp2: 2s 1 p --- 1s 2p
