Question

Is Helium an element or pure substance or compound?

Answer 1

Hint: Helium is a chemical element with the atomic number 2 and the symbol He. It is a colourless, odourless, tasteless, non-toxic, inert monatomic gas that belongs to the noble gas group of the periodic table. It has the lowest boiling and melting points of all the elements. In the visible universe, helium is the second lightest and most plentiful element.

Complete answer:
Pure substances are substances that have a definite or consistent structure and are made up of only one type of particle. Elements and compounds are subcategories of pure substances.
A material that cannot be broken down further into a simpler substance using standard chemical techniques is referred to as an element. Elements are the building blocks of all matter. More than 119 elements have been found so far, with many more in the process of discovery. Depending on its characteristics, each element has a specific location in the periodic table.
A compound is a pure material made up of two or more elements combined chemically in a set mass proportion. The creation of a compound is always the outcome of a chemical reaction. As a result, a compound lacks the characteristics of its individual parts. The smallest item produced after breaking down the chemical is referred to as a molecule of the substance.
Because if we fill a balloon with just helium gas, it will only contain helium atoms, an element is also a pure substance. Helium is element number 2 on the periodic table, which should inform you that it is, of course, an element.

Note:
Pure substances and mixes are the two types of stuff that may be classified. Pure substances are created by breaking down elements and compounds further. A chemical substance is used to make one type of atom or molecule. A mixture is made up of different atomic or molecular forms that aren't chemically bound together.
