The rounded Atomic Mass of helium is approximately 4 u (atomic mass units). Helium has an atomic mass of about 4.0026 u, which is commonly rounded to 4 for simplicity in many contexts. This value reflects the most abundant isotope of helium, helium-4.
It's just 4.002602 amu
Helium is a non metal element. Atomic mass of it is 4.00.
Helium with an atomic mass of 4.00260
Approximately 4.01
Well, two times four is eight, which would be oxygen.
