Question

Which of the following is the process by which an unstable nucleus is transformed into a more stable nucleus with lower energy?

A. nucleation
B. combustion
C. nuclear decay
D. oxidation
E. nuclear fusion

Answer 1

Nuclear decay is the process by which an unstable nucleus transforms into a more stable nucleus with lower energy.

Step-by-step explanation:

The process by which an unstable nucleus is transformed into a more stable nucleus with lower energy is called nuclear decay. In nuclear decay, a parent nucleus spontaneously disintegrates into a slightly lighter nucleus, accompanied by the emission of particles and/or energy. There are six different types of nuclear decay reactions, including alpha decay, beta decay, gamma emission, positron emission, electron capture, and spontaneous fission. Each type of decay reaction results in the formation of a more stable daughter nucleus.
