The process of radioactive decay that results in the emission of an alpha particle from the nucleus of an unstable nuclide, and causes a change in the identity of the nuclide is ___________.
An unstable nucleus will spontaneously transform into a nucleus with a more stable nucleon balance. When this happens, the nuclide changes identity. In other words, one element may transmute into a different element. That is what happens during ________________.
____________ is the changing of the identity of an element by altering the number of protons in its nucleus through nuclear reactions or radioactive decay.
Nuclear _________ energy is the energy required to break the nuclear force that binds the nucleons in an atomic nucleus.
Two forces at work in a nucleus are electrostatic force and ___________________ force.
An electron or a positron emitted from an unstable nuclide during beta decay is called a(n) ______________.
Protons and neutrons are referred to collectively as __________.
An alpha particle is represented by the symbol _____.
Transuranium _____________ are elements with atomic numbers greater than that of uranium, which is 92.
Neutrons are nucleons made up of __________ and leptons.
The series of nuclides produced by successive radioactive decay of an unstable nuclide until it becomes a stable nuclide is called the ____ series.
Radiation is the emission of energy in the form of particles or _________.
____________ is the energy or particles emitted from a nucleus during radioactive decay or from a nuclear reaction.
The only way to change one element into another is to change the number of ____________ in the nucleus.
___________ is the spontaneous transformation of the nucleus of an unstable nuclide into a lighter, more stable nucleus along with the emission of particles, electromagnetic radiation, or both.
