Quiz 1 Flashcards
List the principal quantum numbers
n, l, ml, ms
n
1, 2, 3, 4... Energy level (the 2 in 2s)
l
determines the shape of the orbital 0 = s 1 = p 2 = d 3 = f
ml
the range of integers between positive and negative orbital shape.
+l … 0 … -l
ms
spin: either +.5 or -.5
Molecular Shapes
Linear Trigonal Planar Tetrahedral Trigonal Bi-pyramidal Octahedral
Atomic Radii trend
Bottom left is best
opposite of ionization energy
Ionization Energy
Top right is best, which means bottom left are more reactive elements.
IE is the amount of energy needed to pull off electrons. First group just gives em up.
Electron Affinity
Amount of energy released when an electron is added to a neutral atom. More negative (energy released) as you move right across table.
Electronegativity
Highest in top right corner of table (ignoring noble gasses)
Measure of the tendency of an atom or molecule to attract electrons.
If EN is similar, a bond is more likely
Gerade
Sigma bonding
Pi anti-bonding
Ungerade
Sigma anti-bonding
Pi bonding
Node types
Angular node:
S has none
P has 1
D has 2
Radial node:
4D has 1
Polarizeability
Large and charged are highly polarizeable
No noble gas configuration helps
Bonding MO vs Non-bonding MO
bonding is lower in energy
