Yea an element can not be broken down anymore but a compound is a group of elements
The only way to break down a compound is through a chemical reaction.
You misunderstand!!!! a compound is broken down into its elemental atoms.
Compound, crystal is not an element so obviously what it is made up of must be a compound <><><><> Crystals can be either an element (diamonds are carbon- and crystalline) or a compound (salt, sugar). Unsure of your meaning of "broken down".
yes
it is a compound, an element is a substance which can not be broken down into anything else through chemical processes
Ammonium compound breaks down into nitrites, and back to nitrates
If it cannot be broken down and has the same properties, it is an element.
A substance that cannot be broken down is a pure substance
A compound
A chemical reaction can't break down an element, but it can break down a molecule.
