... an unstable isotope to a more stable isotope by emission of some type of radiation (alpha, beta, or gamma).
It becomes some other type of atom, i.e., some other isotope or nuclide.
Yes, it is. Nuclear decay is a process that an unstable atom goes through to lose energy and move toward a more stable state. (It may take more than one decay.) In nuclear decay, the nucleus undergoes a change by releasing a particle or particles and electromagnetic energy. Links are provided to related Wikipedia articles and related questions.
That depends on the nuclear decay type. For gamma decay, the identity does NOT change, but for alpha and beta, it does.
That depends on the type of decay, alpha and beta decay change the atom into a different element but gamma decay does not.
All nuclear decay is spontaneous.
Natural chromium is stable and does not decay/

Nuclear change is the change in the nucleus of the atom.
Nuclear reactions change the composition of an atom's nucleus, hence nuclear reaction.
The atom that results from nuclear decay is called the daughter atom. The element of the daughter atom would be called the daughter element. The atom that decayed is called the parent.
That depends on the type of decay, alpha and beta decay change the atom into a different element but gamma decay does not.
Beta decay results in either an increase or decrease in the number of protons, which results in a change in the nuclear charge and produces an atom of a different element.
Uranium may suffer nuclear reactions, nuclear fission, nuclear decay.
nuclear decay
In a nuclear reaction, the nucleus of an atom undergoes a change. Common examples would be alpha decay, beta decay, fusion, and fusion. In each of those cases, different elements are formed in the process. This never happens in ordinary chemical reactions. In chemical reactions, it is the electrons that are involved , not the nucleus of the atom.
During nuclear decay, radioisotopes of one element can change into one or more isotopes of a different element altogether.
Transmutation, which is the change of atoms from one element to another.
