How many times lighter is a helium atom than carbon?
A helium-4 atom is just about 1/3 the mass of a carbon-12 atom.
What is the mass of a single atom of helium?
The atomic mass of Helium is 4.002602. The atomic mass is the combined number of protons and neutrons in the atom.
What has a greater number of atoms a gram of lead or a gram of uranium?
The lead atom is way heavier than the helium atom. We know this by referring to the Periodic Table of Elements. The atomic mass of lead (Pb) is 207, while that of helium (He) is 4. Therefore, we can estimate that an atom of lead is about 50 times heavier than an atom of helium.
The relative atomic mass of an atom can be found by comparing the mass of the atom to the mass of?
The Hydrogen atom. Beware, Hydrogen has an atomic mass based on one proton, as it doesn't have a neutron. So Helium has a mass of four times Hydrogen.
What does the mass number in helium represent?
The mass number in Helium represents how much space a single helium atom takes up (not including electrons, because electrons can be bonded, and my come and go)
What is the mass of a calcium atom compared with the mass of a helium atom?
5
Does the mass of one helium-4 atom equal one atomic mass unit?
The mass of a helium-4 atom is 4,002 602 amu.
How many times lighter is a helium atom than carbon?
A helium-4 atom is just about 1/3 the mass of a carbon-12 atom.
What is the mass of calcium atom compared with the mass of helium atom?
The weighted atomic mass of calcium is 40.1 g/mole and helium is 4.0 g/mole
What is the mass of a single atom of helium?
The atomic mass of Helium is 4.002602. The atomic mass is the combined number of protons and neutrons in the atom.

What is the mass number of helium atom?
The atomic number of helium is 2. Its mass is 4.002602 u ± 0.000002 u
What is the atomic mass for an atom of helium?
4.0026 amu
How many Helium-atoms and Carbon-atoms do you have if you have He-atoms with mass of 40amu and C-atoms with mass of 120amu?
Mass of 1 Helium atom is 4 amu and mass of 1 Carbon atom is 12 amu. So there are 10 helium atoms and 10 carbon atoms
Where is most of the mass located in the helium atom?
down stairs
