Question:
The density of nitrogen gas prepared from air is slightly greater than that of nitrogen prepared by a chemical reaction from a compound of nitrogen due to the presence of the following in aerial nitrogen
The density of nitrogen gas prepared from air is slightly greater than that of nitrogen prepared by a chemical reaction from a compound of nitrogen due to the presence of the following in aerial nitrogen
Updated On: Jul 7, 2022
- Argon
- $CO_2$
- Some nitrogen molecules analogous to $O_2$
- Greater amount of nitrogen molecules derived from $N^{15}$ isotope
Hide Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
he density of nitrogen obtained from air (after the removal of $N_2, CO_2$, moisture etc.) is higher than nitrogen obtained chemically. This is due to the presence of heavier argon in the aerial nitrogen

Group 15 Elements
Group 15 elements are also known as nitrogen group elements or nitrogen family.
It consists of:
- Nitrogen (N)
- Phosphorus (P)
- Arsenic (As)
- Antimony (Sb)
- Bismuth (Bi)
- Moscovium (Mc)
They are present on the right side of the periodic table. All the elements are arranged based on their atomic weight. The elements with similar properties reside in a column called the group.
All Group 15 elements have the electron configuration ns2np3 in their outer shell, where n is the principal quantum number.
