Alpha Decay and Nucleus Composition

Consider a nucleus consisting of 82 protons and 125 neutrons. This isotope is an example of a heavy nucleus that tends to undergo alpha decay.

Alpha decay is a common type of radioactive decay in which an atomic nucleus emits an alpha particle (two protons and two neutrons). After the decay, the resulting nucleus is left with a reduced mass and atomic number.

The question is, after undergoing alpha decay, which of the following statements about the remaining nucleus is NOT true?
