The difference is the photon energy which the waves use Gamma rays have the highest photon energy and microwaves have a lower photon energy,
Electrons in their ground state when excited absorb energy and move to higher energy states.
Absorption is when energy is absorbed by electrons and they move to a higher energy state
Emission is when electrons release that absorbed energy and move to a lower energy state
This release of energy results in emission of light from a flame
The correct answer is
Release energy as they move to lower energy states

Answer:
Group 1
Explanation: because the compound has a formula of M2O , the number of valence electrons of M should be 1.
C = 12
O2 = 16*2= 32
CO2 = (12)+(16*2) = 44
32/44*100 = 72.73%
