Elemental Abundances on Earth
Volatiles
Non volatile
Neon Isotope Ratios
^{20} {\rm Ne} /^{22} {\rm Ne}
Inside the earth:
like solar
In the atmosphere:
like chondrites
Scenario
Scenario 2
Scenario 3
Scenario 4
Scenario 5
Photoevaporation?
Noble Gas ratios in the Mantle
Photoevaporation would deplete He before Ne
Multiple Collisions
He is twice as soluble as Ne -> multiple collisions necessary to reach current ratios
Atmosphere Impact Losses
