Mg which stands for Magnesium is the element to begin with, not a compound.
When you mix an element with a compound, a chemical reaction may occur. The element may react with the compound to form a new compound or may remain unchanged depending on the reactivity of the elements involved.
An element is a part of a compound.
It is an element.
When you mix an element with a compound, the element will interact with the components of the compound but will not form a new compound itself. It may bond to some parts of the compound or remain unchanged depending on the specific elements and compounds involved in the mixture.
It varies with the compound.
a compound is made up of a number of different elements. many times carrying some of the characteristics of that element into that compound

First of all you have mispelled it as 'hellium' . It is 'HELIUM'. It is an element. It atomic No. is '2' , so therefore it is found in position number '2' in the Periodic Table, as 'He'. It is neither a compound nor a mixture. The chemical symbol for helium is 'He '. It's Atomic Mass is '4' It is compsed of 2 protons, 2 neutrons and two electrons. It is the MOST Noble(Inert) of all the elements. It does NOT react with anything. Therefore it exists 'monatomically' (single atoms). Its condensing point is 7 K ( - 266 oC) (Becomes a liquid) Its freezing point is 4 K . ( - 269 oC) (becomes a solid). The name 'helium' is from Classical Greece, and means 'from the Sun'(Helios), because two hydrogen atoms fuse together in the Sun , they form 'Helium'.
