problem

Element \\(X\\) is a rather versatile element found in numerous anions.

Let \\(X_1\\), \\(X_2\\), and \\(X_3\\) represent three different monovalent \\(X\\)-containing anions, and \\(NaX_1\\), \\(NaX_2\\), and \\(NaX_3\\) represent their sodium salts. The oxidation states of \\(X\\) in the 3 anions are all different. \\(X_1\\) contains \\(X\\) in its lowest possible oxidation state.

\\(3 NaX_1 + NaX_2 \\rightarrow NaX_3 + 3 NaOH + A\\) 

\\(2 NaX_3 + 2 HNO_2 \\rightarrow 3 B + 2 NO + 2 NaOH\\)

A and B are gaseous compounds (at standard conditions) containing \\(X\\). A is a binary compound. The mass percentage of \\(X\\) in \\(A\\) is 82.25%.

Determine \\(NaX_2\\).
