The four graphs show different possible relationships between \(\text{ln}\left(\dfrac{{R}}{{R}_0}\right)\) and \(\text{ln}(A).\)
(where \(R\) is the radius of a nucleus and \(A \) is the mass number of the nucleus)
Which of these graphs (1, 2, 3, or 4) correctly represents the relationship between these nuclear parameters?
1. | ![]() |
2. | ![]() |
3. | ![]() |
4. | ![]() |
Atoms have different atomic numbers as well as different mass numbers but have the same number of neutrons is called:
1. | isotopes | 2. | isobars |
3. | isotones | 4. | isodiaphers |
Two nuclei have their mass numbers in the ratio of \(1:3.\) The ratio of their nuclear densities would be:
1. \(1:3\)
2. \(3:1\)
3. \((3)^{1/3}:1\)
4. \(1:1\)
