How can elements be described?
An element is a substance whose atoms all have the same number of protons: another way of saying this is that all of a particular element’s atoms have the same atomic number. Elements are chemically the simplest substances and hence cannot be broken down using chemical reactions.
What does an element symbol look like?
An element symbol is a one- or two-letter abbreviation for a chemical element name. When a symbol consists of two letters, the first letter is always capitalized, while the second letter is lowercase. Element symbols also can refer to alchemy symbols for the elements or to the symbols used to describe isotopes.

Who found helium?
Norman Lockyer
Can we create helium?
Helium is all over the universe—it’s the second-most abundant element. But on Earth, it’s much less common. It can’t be artificially produced and must be extracted from natural gas wells. Over time, helium forms from the decaying uranium and is trapped beneath Earth’s surface, but it takes its sweet time.
Is there a substitute for helium?
Argon can be used instead of Helium and is preferred for certain types of metal. Helium is used for lots of lighter than air applications and Hydrogen is a suitable replacement for many where the flammable nature of Hydrogen is not an issue.
Why does NASA use so much helium?
NASA uses helium as an inert purge gas for hydrogen systems and a pressurizing agent for ground and flight fluid systems. Helium is also used throughout the agency as a cryogenic agent for cooling various materials and has been used in precision welding applications.
