Concept explainers
An explanation corresponding to the statement that there is a possibility for two nuclei to have equal radii even if they have different number of protons and neutrons.
Answer to Problem 1CQ
Explanation of Solution
Nucleus A and nucleus B have different number of protons and neutrons.
The formula to calculate radius of nuclei
Here,
The above statement indicates that radius of nuclei is only dependent on the total number of nucleons present in nuclei.
The total number of nucleons is equal to the sum of the number of protons and number of neutrons. That means, radius of nuclei is dependent on the sum of number of protons and number of neutrons, not separately on number of protons and neutrons.
Conclusion:
Therefore, the radius of nuclei is dependent on the sum of number of protons and number of neutrons, not separately on number of protons and neutrons.

- Suppose you have a pure radioactive material with a half-life of T1/2. You begin with N0 undecayed nuclei of the material at t = 0. At t=12T1/2, how many of the nuclei have decayed? (a) 14N0 (b) 12N0(C) 34N0 (d) 0.707N0 (e) 0.293N0arrow_forward(a) Calculate BE/A for 235U, the rarer of the two most common uranium isotopes. (b) Calculate BE/A for 238U. (Most of uranium is 238U.) Note that 238U has even numbers at both protons and neutrons. Is the BE/A of 238U significantly different from that of 235U?arrow_forward
