:
deficiencia de masa
- Scientists calculate the mass deficiency to determine the nuclear binding energy of isotopes.
Examples
-
In nuclear reactions, the mass deficiency corresponds to the energy released according to Einstein's equation E=mc².
-
The concept of mass deficiency is essential for understanding why nuclei are more stable than their individual protons and neutrons.
-
The mass deficiency in the nucleus is crucial for understanding nuclear stability.
-
A high mass deficiency indicates a strong binding energy.
-
In nuclear physics, the mass deficiency indicates how much mass is lost when protons and neutrons bind together in a nucleus.
-
To find the energy that binds nucleons together, scientists must first calculate the mass deficiency of the atomic nucleus.
-
Understanding the mass deficiency helps researchers develop more efficient nuclear reactions.
Synonyms
The mass difference between a nucleus inside an atom and the total mass of its protons and neutrons

Morphology
A B1 learner who knows 'mass' and 'deficiency' can infer a general sense of 'not enough mass' or a shortfall of mass, so the broad idea is accessible from the constituents. However, the precise technical meaning — a specific small difference between a nucleus's mass and the sum of its protons and neutrons due to binding energy — is specialized and not fully predictable from the words alone, making it only partially transparent.
Etymology
Mass deficiency comes from the image of a nucleus whose mass is partly 'missing' compared with the sum of its protons and neutrons. That deficiency is the mass turned into energy that holds the nucleus together, so mass deficiency means the amount of mass lost when the parts bind into a nucleus.
