Atoms that are heavier than hydrogen were made by nuclear fusion after the big bang. Initially, only the lightest element, hydrogen, was present. However, after the universe cooled, hydrogen atoms fused to form helium. Later, the fusion of these atoms led to the formation of the other elements.

What are two atoms that are heavier than carbon?
Elements with atomic numbers 1-5 are lighter than carbon.
Is carbon dioxide lighter than helium?
No. Carbon dioxide is heavier than helium.
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.
Is a helium balloon heavier than air filled balloon?
No. Helium is lighter than air
What is lighter than helium but heavier than air?
hydrogen
Are heavier atoms heavier than helium atoms?
yes.
What are two atoms that are heavier than carbon?
Elements with atomic numbers 1-5 are lighter than carbon.
What gases are heavier than helium?
Helium exists as a monatomic gas, with atomic mass of 4.0. Thus any gas with a molecular mass higher than 4.0 would be heavier than helium. Hydrogen is the only gas that is lighter than helium; all others are heavier than helium.
Is helium lighter or heavier?
Helium is lighter than air
Is air heavy than helium?
Yes. air is heavier than helium.
Is carbon dioxide lighter than helium?
No. Carbon dioxide is heavier than helium.
Is a helium balloon heavier than air filled balloon?
No. Helium is lighter than air

Are you something of starlight?
Not starlight, but the material we are made of was made in stars. All elements heavier than helium, except for a small amount of lithium, are made in stars. All elements heavier than iron come from supernovae.
What is lighter than helium but heavier than air?
hydrogen
Is 100 aluminum atoms heavier than 100 led atoms?
No. 100 lead atoms are several times heavier than 100 aluminum atoms.
Do hydrogen and helium make up about 50 percent of the atoms in outer space?
While less than 5% of the universe is made up of atoms, hydrogen and helium make up 98% of the atoms in the universe.
