Sulfur was historically called brimstone. (The "brim" part is from an old word meaning "burn", since elemental sulfur can occur as a rock-like substance that does, in fact, burn.)
Pb is a compound.
Ag is the chemical symbol for silver, which is an element. It is not a compound.
HI is a compound. The Compound name is Hydrogen Iodide.
A single displacement reaction is a type of chemical reaction where a free element replaces another element in a compound. This occurs when a more reactive element displaces a less reactive element in a compound, forming a new compound and releasing the displaced element.
Gold is a pure element, not a compound, so it is homoatomic.
Brimstone is a historical term for sulfur which is an element. Sulfur is a naturally occurring element on the periodic table with the symbol S and atomic number 16.
Sulfur does. It appears in the form of a compound with oxygen: sulfur dioxide.

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'.
