Quantum Model Flashcards
What info is needed to determine the energy of a many e- atom?
n and l
What is needed to determine the orientation of an orbital?
M (L)
How to find the # of nodes?
n - 1
What give the number of angular nodes?
l
What gives the number of radical nodes?
n - 1 - L
What can L be for quantum #s?
0 TO n-1
What can m (L) be for quantum numbers?
- L to L
What can Ms be for quantum numbers?
-1/2 or 1/2
First ionization increase on PT
Right, Up
Electron Affinity becomes more +
Down (Some exceptions)
Atomic Radii increases
Left, down
Zeff increases
Up, to the right
What are the metalloids
B, Si, Ge, As, Sb, Te, At
Quantum Number Exceptions
Ag, Au, Cr, Cu, Mo
Electronegativity increases
Right, Up
Ionic radius increases
Down, left
The elements of which group in the pt release the most nrg by gaining an e-?
7A
The elements of which group in the pt absorb the most nrg when gaining an e-?
8A
First ionization exceptions
O -> Se is smaller than left & right column
V is smaller than both sides
