Explain the difference between percent abundance and relative abundance. what is the result when you total the individual percent abundances? the individual relative abundances?

it should be all of them because it asks if you included all of those in your answer

explanation:

atomic mass = 39

number of neutrons = 20

number of protons= 19

electronic configuration = 1s2 2s2 2p6 3s2 3p6 4s1

the number of electron in first shell = 2

number of electrons in n=3 shell = 8
