Answer
Electronic configuration of the non-metallic element with atomic number 9 is = (2,7)
In order to complete it's octet and attain a stable state it requires one electron hence, one electron from the valence shell of two such atoms are mutually shared such that each atom acquires a stable electronic configuration resulting in the formation of single covalent bond between them.
The diagrammatic representation is shown below:
