rules for quantum numbers Flashcards
1
Q
when L equals 1 what cannot be possible
A
mL 2
2
Q
what is the rule for mL
A
-L to +L- cant be bigger or smaller than L
3
Q
what is rule between L and n
A
n can be any number but L has to be anything between n-1
4
Q
n cannot be what
A
0
5
Q
m always must be what
A
1/2
6
Q
all bind formation is
A
exothermic
7
Q
valence bond theory
A
overlap
8
Q
single bonds vs double bonds
A
as bond order goes up bond energy goes up but single bonds have the longest length
9
Q
longer wavelength ..
A
lower energy- red is lowest
10
Q
add each orbital to get n=5
A
s=1
p=3
d=5
f=7
g=9
11
Q
do resonance structures flip back and forth between the structures
A
no
12
Q
ionic bonds are held together by what
A
(+) and (-) forces
13
Q
valence bond theory
A
overlap
14
Q
all bond formation is what
A
exothermic
15
Q
sigma bond is which bond
A
the first bond
