It takes three helium atoms to create one carbon atom through nuclear fusion in stars.
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
The number of helium atoms is 6,022 140 857.10e26.

Carbon atoms can be bonded together.
In the process of nucleosynthesis in stars, three helium atoms (which fuse to form carbon) must come together to create one carbon atom. This fusion process involves a series of nuclear reactions and energy release.
Helium does not form molecules but exists as individual atoms.
1 mol of He contains apx 6.02214x10^23 atoms
Helium has one kind of atom: helium.

A molecule of helium is composed of two helium atoms.
To calculate the number of helium atoms needed to make a chain 1 cm long, divide the length of the chain (1 cm = 10,000 pm) by the diameter of a single helium atom (100 pm). So, 10,000 pm / 100 pm = 100 helium atoms. Therefore, 100 helium atoms placed end to end would make a chain 1 cm long.
