There is a graph of binding energy per nucleon in many textbooks. Since this is mcq, i don't think u have time to calculate individual binding energies. Light nuclei have low binding energies and this increases up to IRON (see graph) Beyond Iron, binding energy per nucleon decreases (proof of lower stability and for radioctivity emission). ∴ Atoms having atomic mass greater than iron(Ar = 56) have lower binding energies.
Answer is A.
NOTE: Iron has the highest binding energy and has a highly stable nucleus (very very rare to find radioactive iron in nature)
 

FAQ: Which atoms have lower binding energies than iron?

What is binding energy problem?

The binding energy problem is a theoretical and experimental challenge in the field of nuclear and particle physics. It refers to the discrepancy between the observed mass of atomic nuclei and the predicted mass based on the individual masses of their constituent particles.

Why is binding energy problem important?

The binding energy problem is important because it helps us understand the fundamental nature of matter and the forces that hold it together. It also has practical applications in fields such as nuclear energy and astrophysics.

What causes the binding energy problem?

The binding energy problem is caused by the fact that the mass of a nucleus is always less than the sum of the masses of its individual particles. This is due to the release of energy when the particles come together to form the nucleus, as described by Einstein's famous equation E=mc².

How is the binding energy problem being studied?

Scientists are studying the binding energy problem through a combination of theoretical and experimental methods. This includes using particle accelerators to study the structure of nuclei and developing models and theories to explain the observed data.

Can the binding energy problem be solved?

At present, the binding energy problem remains an open question in physics. While significant progress has been made in understanding and describing the phenomenon, a complete solution has not yet been found. Further research and advancements in technology may lead to a better understanding of the problem in the future.
