A helium atom is four times lighter than a carbon atom. This is because helium has two protons and two neutrons in its nucleus, while carbon has six protons and six neutrons. The atomic mass of helium is approximately 4 atomic mass units, while the atomic mass of carbon is approximately 12 atomic mass units.

What is the diameter of the helium atom?
The nucleus of a Helium atom contains two protons and two neutrons, protons and neutrons are measured in Daltons, and a Helium atom is about 4 Daltons
What more does a carbon atom have than a helium atom?
A carbon atom has more protons, neutrons, and electrons than a helium atom. This gives carbon different chemical properties and the ability to form larger and more complex molecules compared to helium.
What atom is 4.65 times as great as the mass of carbon 12?
Helium has atomic mass 4.003 a.m.u.
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.)
Is an alpha particle identical to the nucleus of a carbon atom?
No, it is identical to the nucleus of a helium atom.
