Lecture 1 Flashcards
What is the definition quantum numbers?
labels given to electrons
What is the Schrodinger wave equation?
used to find the allowed energy levels of quantum mechanical systems
What is the symbol for the principle quantum number
n
What is the symbol for the Orbital Angular Momentum quantum number?
l
What is the symbol for the magnetic quantum number?
ml
What is the symbol for the spin quantum number?
ms
What does the principle quantum number describe?
Describes the row of the periodic table .
it refers to the size of the orbital and the energy level an electron is placed in. The number of subshells, or l, describes the shape of the orbital.
What does the orbital angular momentum quantum number describe?
Describes the shape of an orbital.
s ; l = 0
p; l = 1
d; l = 2
What does the magnetic quantum number describe?
The orientation of the orbital
What is the ml value for Px ?
-1
What is the ml value for py?
1
What is the ml value for pz?
0
What does the spin quantum number describe?
the spin of the electron
What are the two values that any spin can take?
+1/2 and -1/2
what does diamagnetic mean?
compounds with paired electrons
