(48 cards)
How is the speed of light related to wavelength or frequency?
C = λv
How many e for a d-orbital
10, L = 2
How many e in an s orbital
2, l = 0
How many e for an f orbital
14, l = 3
How many e for a p- orbital?
6, L = 1
How to find angular nodes:
Determined by L
How to find radial nodes?
Rn = n -1 -l
Total nodes?
N-1
Quantum numbers:
N, L ( < N), M(L) (+- L to 0), M(S) +-1/2
Number of orbitals?
L * 2 + 1
Periodic table shell summ:
(Left to right): n + (s for left, p for right), n-1 (d) for metals, 4 for top and 5 for bottom f for the bottoms
Single photon energy
E = HV = HC/lam
1/2mv^2 =
HV - (threshhold)
change in energy levels -
R(1/final^2 - 1/initial^2)
an ennergy levels E =
-R(1/n^2)
order of electromagnetic radiation
radio - microwave - infrared - visible - Ultraviolet - x-ray - Gamma
how many petals has a: s-orbital, p-orbital, d-orbital, f-orbital?
1, 2, 4, 6
how to find radial nodes
draw a circle
hands rule:
1 orbital each before paring (spread out e)
Aufbau principal:
lowest e to highest
Pauli exclusion:
paired spins and unique quantum nums
Effective nuclear charge:
num protons - shielding e (inner electrons/noble gas)
ionization energy is strongest when:
you are trying to remove something from the core
electromagnetic spectrums for visible and UV are known as:
Balmer and lyman
