Answer 1

Answer:

1. Nearly all helium on Earth is a result of radioactive decay. The decay product is primarily found in minerals of uranium and thorium.   In what is called radioactive emission of "alpha particles" the atom of, say uranium, spits out particles in the form of two protons and two neutrons--a helium nucleus.

2.Helium is obtained through natural gas as it is extracted from the ground. The helium is a result of the decay of thorium and uranium. As these elements decay, they release an alpha particle. That alpha particle is the nucleus of a helium atom.

3.Natural gas is separated into its major components through a distillation process known as fractional distillation. Sometimes this name is shortened to fractionation, and the vertical structures used to perform this separation are called fractionating columns. In the fractional distillation process, the nitrogen and methane are separated in two stages, leaving a mixture of gases containing a high percentage of helium. At each stage the level of concentration, or fraction, of each component is increased until the separation is complete.

Answer 2

Answer:

1. A natural rare element on Earth. It is naturally found  on the Earths ground.

2. Helium is obtained from decaying radioactive elements such as Uranium, and/or by liquefying air in order to separate the different elements.

3. It depends on the scale needed. For large use the processes of fractional distillation is used, this process separates liquids based on their boiling points. It can also be obtained from decaying radioactive elements.

Explanation:

Helium is a natural colorless gas that is naturally found on Earth's grounds. It was discovered by astronomers Pierre Janssen and Sir Joseph Lockyer  in 1868 . It has a low density, chemical reactivity, low temperature, and boiling point. This gas is used for a number of things including:

• Airbags
• MRI magnets
• Computer and mobile phone chips
