Answer 2

HI there !!

I am giving the approx. masses of the elements

1.Hydrogen = 1 u
2.Helium = 4 u
3.Lithium = 6 u
4.Beryllium = 9 u
5. Boron = 10 u
6.Carbon = 12 u
7.Nitrogen = 14 u
8.Oxygen = 16 u
9.Fluorine = 19 u
10.Neon = 20 u
11.Sodium =23 u
12.Magnesium = 24 u
13. Aluminium = 27 u
14.Silicon = 28 u
15.Phosphorus = 31 u
16. Sulphur = 32 u
17.Chlorine = 35.5 u
18.Argon = 40 u
