The Lewis structure of
Diimide (N₂H₂) is shown below.
In this molecule two Nitrogen atoms attached to each other through a
double bond are further attached to one one Hydrogen atom. Also, each Nitrogen atom carries one
non-binding electron pair (
Lone Pair) (Highlighted RED).
Result: Option-C (<span>each nitrogen has one nonbinding electron pair) is the correct answer.</span>
Density is an intrinsic property, so it is independent of the amount of substance present: one gold coin would have the same density as a solid gold boulder.
So if the density of gold is 19.3 g/cm³, the density of a bar of gold and the pieces into which the bar is cut would all be 19.3 g/cm³.

The Chlorine and fluorine atoms are the most electronegative.
So, option D and E is correct one.
The atom of a given chemical elements having tendency to attract bonded pair of electron toward itself is called electronegativity. The electronegativity of atoms is affected by both its atomic number and distance at which its valence electrons resides from the charged nucleus.
The electronegativity of the elements is increases on moving left to right in the period of periodic table while decreasing on moving top to bottom in the group of periodic table .
Example:
The elctronegativity of fluorine atom = 3.98
The elctronegativity of chlorine atom =3.16
The elctronegativity of carbon atom = 2.25
The elctronegativity of phosphorus atom = 2.19
The elctronegativity of silicon atom = 2.58
