The coordination number of a metal ion in a compound is the number of atoms, ions, or molecules that a central atom or ion holds as its nearest neighbours in a complex or coordination compound or in a crystal.

In the case of NaH, sodium (Na) is an alkali metal and hydrogen (H) is a nonmetal. When they form a compound, it is an ionic compound. In ionic compounds, the coordination number is determined by the relative sizes of the ions.

In NaH, each sodium ion is surrounded by 6 hydrogen ions. Therefore, the coordination number of Na in NaH is 6.
