Sodium (Na) is a necessary element (used in ionic form) for the maintanence of the lives of a number of animals and plants. It is what makes the oceans salty.
Sodium is used to improve the structure of certain alloys, to descale metal, and to purify molten metals.
An alloy of sodium with potassium, NaK, is also an important heat transfer agent.
A sodium and chlorine(Cl) compound is also used as a common seasoning (NaCl, or table salt).
Metallic sodium is is also used in the manufacture of esters and in the preparation of organic compounds.

Sodium is an alkali metal.
Ionic
Sodium is an element. Chemical symbol Na Number 11
Sodium has 11 protons.
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.
It is the element Sodium.
Sodium is not a mixture. It is an element.
Sodium is an alkali metal.
A sodium atom, atomic number 11.
Table salt is a compound - sodium chloride, NaCl - not an element.
