Both Sodium and Hydrogen have charges of plus one so no, alone they do not bond.
Hydrogen can have either a +1 or a -1 charge. Therefore you can have NaH, it is called Sodium Hydrazine.
Sodium itself is not flammable. But if it has an ionic bond or in other compounds it can be.
Covalent bond can exist in any type of compounds.
Many compounds between nonmetals have this type of bond.
Some examples of compounds are water (H2O), carbon dioxide (CO2), sodium chloride (NaCl), and glucose (C6H12O6). These compounds are formed when two or more different elements chemically bond together.
Sodium fluoride is an ionic compound.
