Electron configuration Flashcards
What is the principal quantum number (n)?
Related to the size and energy of an orbital.
What happens when the n value gets bigger?
- The orbital becomes bigger
- The electron spends more time away from the nucleus
- The energy increases since the electron is less tightly bound to the nucleus (energy is less negative)
What is the angular momentem quantum number (l)
Related to the shape of the atomic orbitals
what subshell is l = 0?
s
What subshell is l = 1
P
What subshell is l = 2
d
What subshell is l = 3
f
What subshell is l = 4
g
What is related to the Magnetic quantum number (ml)
Is related to the orientation of the orbital relative to the other orbitals in the atom
What is related to Electon spin quantum (Ms)
related to the direction of the electrons spin
Either be 1/2 to -1/2. No two electron to can spin the same in in on
What is the Aufbau principal
Atoms want to use the least amount of energy possible, filling up the orbtals with less energy first.
What is Pauli’s exclusion principal?
No two electron in the same orbital can have the same quantum numbers (the spins will be different)
Hund’s rule
One electron will occupy every orbital before there is 2 electrons in the same orbital
