Question

The packing fraction for 7N¹⁴ isotope, whose mass is 14.003 amu a) 3× 10-³ b) 2.1×10-⁴ c) 1.00002 d) 0.9​

Answer 1

Answer:

verified by topper

The expression for packing fraction is

Packingfraction=

massnumber

isotopicmass−massnumber

×

10

4

When the packing fraction has negative value, the mass number is more than isotopic mass. This means that some mass is converted into binding energy.

This stabilizes the nucleus.

Positive value of packing fraction implies for the unstability of nucleus.

Thus this concept primarily discusses the stability of the nucleus.

Thus, Both S and E are correct but E is not correct explanation of s

Answer 2

Answer :

(B) 2.1×10-⁴

The packing fraction is defined as the ratio of the volume occupied by the atoms in a solid material to the total volume of the material. The value of 2.1×10-⁴ for 7N¹⁴ isotope represents the ratio of the volume of the atoms to the total volume of the material, indicating that a small fraction of the total volume is occupied by the atoms in the material.

Explanation :

The packing fraction is a measure of the volume occupied by atoms or ions in a crystal structure. It is defined as the ratio of the volume occupied by the atoms to the total volume of the crystal structure. In this case, the packing fraction for the 7N¹⁴ isotope with a mass of 14.003 amu is 2.1×10-⁴.

This value represents the fraction of the total volume of the crystal structure that is occupied by the atoms of the 7N¹⁴ isotope. The smaller the value of the packing fraction, the more dispersed the atoms are in the crystal structure, which can affect the physical properties of the material. On the other hand, a larger packing fraction indicates that the atoms are more closely packed together, which can lead to stronger interatomic interactions and a different set of physical properties.

It is important to note that the packing fraction is dependent on several factors, including the crystal structure, size and shape of the atoms, and the presence of any defects or impurities in the crystal. The packing fraction is widely used in materials science and solid-state physics to characterize and compare the properties of different materials.
