Question

A non metallic atom(at.no.9) forms a molecule of same containing a single covalent bond

Answer 1

A non- metallic atom with atomic number 9 (Flourine) has 7 valence electrons.Therefore, it needs one more electron to complete its octet.Thus, it combines with another atom of the same element to form a molecule having single covalent as follows:

Answer 2
