O2 has a bond length of 1.21 Å (1.21 x 10-10 meters).
H2 has a bond length of 0.74 Å (0.74 x 10-10 meters).
On average then, oxygen atoms in an Oxygen molecule are alomost twice as far apart as the average distance between hydrogen atoms in a Hydrogen molecule.
The sun produces energy by fusing hydrogen atoms into helium atoms. This is a nuclear fusion that occurs at the sun's core.
The answer is 8,1547.10e25.
helium
No. The difference between them is that helium atoms have electrons, and alpha particles don't.
1 mole = 6.0 x 1023 atomsSo, 4 mole = 24 x 1023 atoms or 2.4 x 1024 atoms
Helium is made of atoms.
No Helium is made of atoms
The number of helium atoms is 6,022 140 857.10e26.
Helium is made up of helium and oxygen is made up of oxygen. Both helium and oxygen are elements, so they can't be broken down into anything simpler without breaking apart the atoms.
the ballon would explode when it is in space, because the is almost nothing in space. so the helium atoms would spread and the balloon would pop.
Helium atoms.

There are two nitrogens and four oxygens.
Helium does not form molecules but exists as individual atoms.
There are 5 atoms in silver nitrate (1 silver, 1 nitrogen and 3 oxygens).
The helium atoms move quickly in all directions. This is cap
