Explanation:

different methods: distillation,Chromatography,Centrifuging, Evaporation, filtration

the electron configuration that you gave me has 16 electrons ergo it has 16 protons ergo it is the element sulfur.

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
