Chlorine is an element, because it is in the Periodic Table.
It forms the elemental molecule Cl2 ( Cl - Cl)
It is a green extremely poisonous gas. Not found directly in nature , but only as it anions Cl^- & ClO^- etc., in NaCl ( Sodium Chloride - common salt) , and Ca(ClO)2 ( a bleach).
the element chlorine is very common. its used in most disinfectant cleaners and used in Swimming Pools.
it is abundant in nature.
Chlorine is an element.
No such substance as 'sodium chlorine'. I think you mean 'sodium chloride'. I which case it is an ionic compound. Separately , sodium(metal) is an element and chlorine(gas) is an element. They both appear in the Periodic Table. 'Mixture', does not come into question.
No. It's a molecular element.
ClO4 is not a compound, it exists as ClO4-, which is a polyatomic ion called the perchlorate ion. Some positive ion such as potassium or ammonium must be present to balance the charge and form a compound.
Cl, chlorine is an element, Cl2 is the molecular form of the element. When 'free' chlorine is so reactive that it will react with itself to form diatomic (2 atoms) molecules, but it is still an element.

Chlorine is an element on the periodic table. If you look, its average atomic mass is 35.5 amus. It would be a compound if it was 'connected' with another element, ie Hydrogen. HCl is considered a compound, but chlorine (Cl) alone is just an element.
