no, its inorganic. this looks like the pentahydrate of sodium hydrogen phosphonate, Na2HPO3.5H2O , (often called sodium hydrogen phosphite) note P has oxidation number +3.
An organic compound cannot have the formula C2H7 because carbon (C) forms four bonds and hydrogen (H) forms one bond, so the maximum number of hydrogens that can be attached to two carbon atoms is 6 (C2H6). Having 7 hydrogens would result in carbon having a pentavalent configuration, which is energetically unfavorable and violates the octet rule.
Hydrogen chloride is not an element; it is a compound and has no atomic number!
In the compound hydrides such as lithium hydride (LiH) or sodium hydride (NaH), hydrogen has an oxidation number of -1.
Hydrogen it depends on the other element if it is part of a compound
A hydrogen atom can bond with up to one other atom in an organic compound.

Since H atoms have one valence electron, they can bond with only one element, whether in an inorganic or organic compound.
This number is 4.
