Lights acts as what? Particle and wave. 
 
Wavelength The distance (m) of waves from peak to peak. Short: x-ray (red), long: infrared 
(blue) 
Short - higher energy 
Long - lower energy 
 
Frequency (V) The number of wavefronts per second. Highest: x-ray 
 
Velocity of Light C = 3.00 X 10^8 
= wavelength X frequency 
 
Amplitude The intensity, height of peaks of waves. Highest: blue light

What is the maximum number of electrons that can have the quantum numbers n 
= 3, ℓ = 2, mℓ = -2? 
The Pauli exclusion principle states that no two electrons in a given atom can share the 
same set of four quantum numbers (n, ℓ, mℓ, ms). This set of quantum numbers contains

CHEMISTRY A LEVEL WITH SATISFIED SOLUTIONS 
 
 
 
What are the two elements which are exceptions to the electron configuration? - CORRECT-The two exceptions for this is copper and chromium. In both cases, the 4s subshell contains only one electron, even though there are electrons in the 3d subshell. 
 
 
 
To explain this, its because the 3d subshell is more stable when it is either half full, or completely full. 
 
 
 
So in the case of chromium, by having only one electron in the 4s subshell, ...
