Obsidian is a naturally occurring volcanic glass composed primarily of silicon dioxide, which is a compound made up of the elements silicon and oxygen. Therefore, obsidian is not an element but a mixture of elements in compound form.
Obsidian is neither an element nor a compound. It is a naturally occurring volcanic glass formed when lava cools rapidly without crystal growth.
ice water is a mixture of solid water and liquid water. the two components are different phases of the same compund , namely water.
Iodine is a chemical element; not a mixture, not a 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'.
