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.
All nuclear decay is spontaneous.
Natural chromium is stable and does not decay/
Matter can be made to undergo nuclear decay in reactors, but it is a process that occurs spontaneously in nature.
transmutation of elements... the thing alchemists sought to do
That depends on the nuclear decay type. For gamma decay, the identity does NOT change, but for alpha and beta, it does.
Uranium may suffer nuclear reactions, nuclear fission, nuclear decay.
During nuclear decay, radioisotopes of one element can change into one or more isotopes of a different element altogether.
what are the forms of nuclear decay
nuclear decay, such as alpha decay or beta decay.
In a nuclear decay sequence it is possible for heavier atoms to decay to a lighter element.
Yes, radioactive decay results in the release of nuclear energy. The radioactive decay of an atom is the result of changes in the atom's nucleus, so energy released will be nuclear energy by definition.
Alpha nuclear decay
All nuclear decay is spontaneous.
"Chemical reaction rates vary with the conditions of the change but nuclear rates do not."
yep, sure are
The radioactive decay of radium is a nuclear change. This differentiates the transformation from a chemical or physical one.
