the atomic radius of a nitrogen atom is 71 pm. what is the distance between the nuclei of two bonded nitrogen atoms in a n2 molecule?\na 35 pm\nb 70 pm\nc 142 pm\nd 212 pm
Answer
Explanation:
Step1: Recall atomic - radius concept
The distance between the nuclei of two bonded atoms of the same element in a molecule is equal to twice the atomic radius of a single atom.
Step2: Calculate the distance
Given the atomic radius of a nitrogen atom $r = 71$ pm. The distance $d$ between the nuclei of two bonded nitrogen atoms in $N_2$ is $d = 2r$. Substitute $r = 71$ pm into the formula: $d=2\times71$ pm. $d = 142$ pm
Answer:
C. 142 pm
