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 else can I help you with?
Does a mole of carbon atoms have three times greater then helium?
No, a mole of carbon atoms has the same number of atoms as a mole of helium atoms (Avogadro's number, which is about 6.022 x 10^23 atoms). The difference lies in their atomic masses, as carbon atoms are heavier than helium atoms.
What are two atoms that are heavier than carbon?
Two atoms that are heavier than carbon are nitrogen and oxygen. Nitrogen has an atomic number of 7 and a higher atomic mass than carbon, while oxygen has an atomic number of 8 and is even heavier than nitrogen.
Is a helium balloon heavier than air filled balloon?
No. Helium is lighter than air
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.
What is lighter than helium but heavier than air?
hydrogen
Are heavier atoms heavier than helium atoms?
yes.
What is heavier nitrogen or helium?
Nitrogen is the heavier gas (mass of 28) compared to helium (mass of 4).
Does a mole of carbon atoms have three times greater then helium?
No, a mole of carbon atoms has the same number of atoms as a mole of helium atoms (Avogadro's number, which is about 6.022 x 10^23 atoms). The difference lies in their atomic masses, as carbon atoms are heavier than helium atoms.
What are two atoms that are heavier than carbon?
Two atoms that are heavier than carbon are nitrogen and oxygen. Nitrogen has an atomic number of 7 and a higher atomic mass than carbon, while oxygen has an atomic number of 8 and is even heavier than nitrogen.
Is helium a molecule?
Helium is an atom. Heavier elements have molecules.
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.
Which is heavier hydrogen or helium?
Helium is heavier than hydrogen. Hydrogen is the lightest and simplest element in the periodic table, while helium is the second lightest element.
Is helium lighter or heavier?
Helium is lighter than air
Is air heavy than helium?
Yes. air is heavier than helium.
Is 100 aluminum atoms heavier than 100 led atoms?
No. 100 lead atoms are several times heavier than 100 aluminum atoms.
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.
