What does the mass number in helium represent?
The mass number in Helium represents how much space a single helium atom takes up (not including electrons, because electrons can be bonded, and my come and go)
What takes longer ice melting or water freezing?
What takes longer to melt ice or freeze water?
What fusion in stars occurs to create the element helium?
Hydrogen undergoes nuclear fusion in the core of the sun to form helium.
Is helium produced only in the cores of stars?
No. Helium nuclei are a common product of nuclear fission, as takes place in nuclear explosions and reactors. These nuclei then pick up electrons from other atoms and become whole helium atoms.
How can you determine that helium takes up space?
There are undoubtedly some molecules of helium scattered around in the space between the stars and dust clouds, as there are atoms of other elements, but for all practical purposes space can be treated as a vacuum - a place where there are no atoms of any kind.
Diffusion of light in the atmosphere takes place due to what?
Helium
Why is helium soon to be a scarce commodity?
Helium is formed underground when radioactive particles of larger atoms such as uranium and radon decay into smaller atoms such as helium. This process takes millions of years. However, it takes very little time to use up helium. Once the earth's existing stores of helium are used up, it will take another million years to build up new ones. In the mean time, helium will be scarce.
Which gas helium or oxygen takes up most of earth atmosphere?
Well, neither one of them takes up most of the atmosphere. But oxygen takes up a lot more of it than helium. Oxygen makes up close to 20% of the air we breathe. Helium only makes up a tiny percentage - it's almost immeasurably small.

How can you demonstrate helium takes up space?
uhmmmm.?!(: i really dont know(: lol:]
Higher speeds require more space for a maneuver?
Yes, at high speed it takes longer to change your direction, for example.Yes, at high speed it takes longer to change your direction, for example.Yes, at high speed it takes longer to change your direction, for example.Yes, at high speed it takes longer to change your direction, for example.
