sodium chloride, sodium carbonate, sodium bicarbonate
Not a lot! Sodium is a reactive metal, nitrogen is an unreactive diatomic gas. Sodium forms compounds where it loses an electron, to form the Na+ ion. Nitrogen forms covalent compounds such as NH3 and ionic compounds where it gains three electrons to form the N3- ion.
too generic,bonding
Sodium chloride oxygen and calcium
Actually there are lots of elements which are commonly found only in compounds rather than in their pure elemental form. Sodium, magnesium, calcium, hydrogen come immediately to mind, but there are lots more.
-Acetic acid and sodium acetate -Citric acid and sodium salts -Phosphoric acid and sodium/potassium salts

Helium doesnot form any compounds.
No.Sodium is an example of an element, a substance that consists of only one type of atom (in this case, the sodium atom).A compound is a pure substance that consists of more than one type of atom (for instance, sodium chloride, which consists of sodium atoms and chlorine atoms). Compounds can be separated into their individual elements by chemical reactions.

Actually there are lots of elements which are commonly found only in compounds rather than in their pure elemental form. Sodium, magnesium, calcium, hydrogen come immediately to mind, but there are lots more.
Examples: NpO2, NpCl3, NpF3.
The formulas of compounds contain as many unique symbols as the number of elements they contain. Sodium hypochlorite (bleach) has the formula NaClO which means that it contains the three elements sodium (Na), chlorine (Cl) and oxygen (O).

Sodium and lithium chlorides are formed.
order
There are no common compounds of argon. The only known compound is argon fluorohydride but that is hardly common. Also, argonium (argon hydride) molecules have been identified in the Crab nebula, but that can hardly be described as common.
