Answer 2

heya

here is ur answer

=============================

✴ atomic weight or atomic mass number is same.

1. hydrogen - 1.008

2.helium - 4.00

3.lithium - 6.94

4. berylium - 9.01

5.boron - 10.81

6.carbon - 12.01

7.nitrogen - 14.01

8. oxygen - 16.00

9.florine - 19.00

10. neon - 20.18

11.sodium - 22.99

12.magnesium - 24.31

13.aluminium - 26.98

14.silicon - 28.09

15. phosphorus - 30.97

16.sulphur - 32.07

17.chlorine - 35.45

18.argon - 39.96

19.potassium - 39.10

20.calcium - 40.08

21. scandium - 44.96

22.titanium - 47.88

23.vanadium - 50.94

24.chromium - 52.00

25.manganese - 54.94

26.iron - 55.85

27.cobalt - 58.93

28.nickel - 58.69

29.copper - 63.35

30. zinc - 65.39

✴ atomic weight is just the double of atomic number (approx)
