in the atmosphere
There are no electrons present in a helium atom in its second energy level.
The big bang produced the helium no present in the sun's core. The universe cooled down enough after the big bang to form the formation of helium and hydrogen.
To find the number of moles present in 205 g of helium, we need to use the molar mass of helium, which is approximately 4 g/mol. Divide the given mass by the molar mass to get the number of moles. In this case, 205 g / 4 g/mol = 51.25 moles of helium.
Hydrogen and helium are both present in significant amounts in the universe. They are also both light gases that have low atomic masses.
Yes, Neptune's atmosphere contains helium, along with other gases such as hydrogen and methane. Helium is present in trace amounts and plays a role in the overall composition and dynamics of Neptune's atmosphere.
helium is not present
Air is a mixture of gases in which helium is present in atmosphere.It is mostly present in oxygen tanks used by sea divers and in balloons.
The number of moles of helium is 0,32.
Why helium, of course!
Mainly hydrogen and helium.
H2O or water doesn't have any helium in it.
There are no electrons present in a helium atom in its second energy level.
helium doesn't form any compound
Nitrogen, Oxygen, Helium
heluim are 4 nucleide
Hydrogen, helium, carbon dioxide, and calcium.
Helium is named from the Greek word helios - which means 'the sun'. It got this name because it was known to be present in the Sun.
