it is a compound, an element is a substance which can not be broken down into anything else through chemical processes
It isn't on the periodic table since it is not a single element but a compound made of two elements: hydrogen and chlorine.
Yes, pyridoxine hydrochloride is a chemical compound. It is the hydrochloride salt form of pyridoxine, which is a form of vitamin B6. It is commonly used in dietary supplements and medications to treat vitamin B6 deficiency.

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'.
Mixture
if it dissolves its a compound if not its an element.
NO = Nitrous Oxide - compound No = Nobelium - element
