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:

president carter called the victims of kidnapping "victims of terrorism and anarchy" and added that the united states was not going to give in to blackmail. in the united states, they see hostage-taking as an outrage on the part of the islamist movement that violated the principle of international law on the immunity and inviolability of diplomats and their embassies.
