Which element is four times the atomic mass of helium?
This element is oxygen.
What is the atomic mass average for helium?
Helium is a non metal element. Atomic mass of it is 4.00.
What element has an atomic mass of 4.0?
The element with an atomic mass of 4.0 is helium. Helium has an atomic number of 2, which means it has two protons in its nucleus. It also has two neutrons, giving it an atomic mass of 4.0.
Why is helium heavier than air?
Helium is lighter than air because of atomic mass. Helium is element number two, whereas oxygen is element number 8. Oxygen has an atomic mass of 16, and helium has a mass of 4, so helium is 4 times lighter than air. (Atomic mass is the total mass of protons, neutrons, and electrons in a single atom.)
4.002 is the atomic mass of which element?
4.002 is the atomic mass of helium, element number 2 on the periodic table. It is a light, colorless, odorless gas that is the second most abundant element in the universe. Helium is commonly used in balloons and cryogenics due to its low boiling point.

Is the element with the least atomic mass hydrogen or is it helium?
The answer is Hydrogen.
What does it mean if helium has mass?
atomic mass is the number of protons in that element molecule.
