HELP NEEDED!! How is the element Helium obtained and separated from other nearby substances?

Helium is generated underground by the radioactive decay of heavy elements such as uranium and thorium. Part of the radiation from these elements consists of alpha particles, which form the nuclei of helium atoms. ... Helium can also be produced by liquefying air and separating the component gases.

Explanation:

Helium is one of the basic chemical elements. In its natural state, helium is a colorless gas known for its low density and low chemical reactivity. It is probably best known as a non-flammable substitute for hydrogen to provide the lift in blimps and balloons. Because it is chemically inert, it is also used as a gas shield in robotic arc welding and as a non-reactive atmosphere for growing silicon and germanium crystals used to make electronic semiconductor devices. Liquid helium is often used to provide the extremely low temperatures required in certain medical and scientific applications, including superconduction research.

Explanation:

Now and again he was more direct, as in this essay on “Political Authority” in which he defended the idea of “the consent of the governed” (a basic demand of democrats) as well as denouncing the idea that “might makes right.” He thought that most European governments had acquired their power by means of violence, which ...
