Name: Helium Symbol: He Atomic Number: 2 Atomic Mass: 4.002602 amu Melting Point:-272.0 °C (1.15 K, -457.6 °F) Boiling Point:-268.6 °C (4.549994 K, -451.48 °F) Number of Protons/Electrons: 2 Number of Neutrons: 2 Classification: Noble Gas Crystal Structure: Hexagonal Density @ 293 K: 0.1785 g/cm 3 Color: colorless Atomic Structure. Helium's atomic mass is 4.003, (carbon is 12.0107, oxygen is 15.9994). Multiply the atomic mass number by the molar mass constant (defined as 0.001 kg/mol. Or 1 gram/mol.), thus making the molar mass 4.003 grams/mol.
