Question

Which of the following does not describe nitrogen:-
(A). Nitrogen is a chemical element with atomic number $7$ .
(B). Nitrogen is a non metal with an electronegativity of $3.04$ .
(C). Nitrogen is highly reactive due to high bond dissociation energy.
(D). The triple bonds in Nitrogen atoms makes it difficult to convert nitrogen into other compounds.

Answer 1

Hint : Nitrogen is a group $15$ element. Group $15$ elements are also called pnictogens. Nitrogen is the first member of the pnictogen family. Nitrogen was discovered by a Scottish based scientist Daniel Rutherford in $1772$ . The name nitrogen was given by a French scientist named Jean-Antoine-Claude Chaptal in $1790$ .

Complete Step By Step Answer:
The correct answer for the wrong statement regarding the wrong statement related to nitrogen is (C). Nitrogen is highly reactive due to high bond dissociation energy.
Nitrogen is the $7$ element of the periodic table thus having an atomic number equal to $7$ . Thus option (A). Nitrogen is a chemical element with atomic number $7$ is correct.
Nitrogen is a p- block element. P- block elements are mostly nonmetals and thus nitrogen is a non metal. Thus option (B). Nitrogen is a non metal with an electronegativity of $3.04$ is correct.
Nitrogen has $7$ electrons in total and requires only $3$ more electrons to gain the nearest noble gas configuration of neon. Thus two nitrogen atoms combining together leads to a triple bond and makes nitrogen gas. Thus option (D). The triple bonds in Nitrogen atoms makes it difficult to convert nitrogen into other compounds.

Note :
Nitrogen is a p-block element and is the third most electronegative element of the periodic table. Nitrogen is very less reactive because of the triple bond formed between two nitrogen atoms for the preparation of the nitrogen gas. Nitrogen is very essential for life, nitrogen is present in amino acids which leads to D.N.A and other important and essential items.
