The total number of valence electrons is 20.(1 from hydrogen, 5 from nitrogen, and 7 from each fluorine so 14 for both) connect all the atoms with a single bond( each bond counts as 2) so far there is 6 electrons so you need to fill in the rest of the 14 and you get the result in the picture.
Answer:
sigma bond
represents two electrons
Explanation:
The bond between hydrogen and oxygen is sigma bond because the bond between hydrogen and oxygen is covalent means sharing of electron takes place between two atoms and we know that sigma bond is also occurs in a covalent bond in which overlapping of atomic orbitals or hybrid orbitals along the bond axis occurs. Both also represent two electrons because both atoms share one electron each so we can say that the two atoms represents two electrons.
