Question

Atomic mass of first 30 elements without decimals

Answer 1

Explanation:

Hydrogen -1 Helium-4 Lithium = 7 Beryllium = 9 Boron = 11 Carbon = 12 Nitrogen = 14 Oxygen = 16 Fluorine = 19 Neon = 20

Sodium = 23 Magnesium = 24 Aluminum = 27 Silicon = 28 Phosphorus =31 Sulfur = 32 Chlorine =35 Argon = 40 Potassium = 39 Calcium = 40

Scandium = 45 Titanium = 48 Vanadium = 51 Chromium = 52 Manganese = 55 Iron = 56 Cobalt =59 Nickel =59 Copper - 63 Zinc - 65
