Carbon-14 was the answer given; however, through a painful grading experience I found it is wrong. The actual answer is ( Particles and Energy)
Plutonium is a radioactive element that decays over time, transforming into other elements through a series of radioactive decays. When plutonium decays, it releases energy in the form of radiation and transforms into a different element. This process continues until the plutonium is no longer present.
When a radioactive element decays, it releases energy in the form of radiation (such as alpha or beta particles). The decay changes the element into a different element or isotope, which may also be radioactive. This process continues until a stable non-radioactive element is formed.
That's what an atom emits when it decays.
Uranium is radioactive because its atomic structure is unstable, leading to the emission of particles and energy as it decays. This process is known as radioactive decay, which releases radiation in the form of alpha and beta particles, as well as gamma rays.
Francium (Fr) is a natural radioactive element, extremely rare.
When an element "decays", it forms a different element. This is the definition of "decay" when referring to radioactive elements.
Radioactive elements have unstable nucleii. When an unstable nucleus decays it emits energy in the form of electromagnetic waves and heavy particles and in the process forms new nucleii.
unstable, radioactive
Radioactive rocks generate electricity through a process called nuclear fission. When the radioactive material decays, it releases energy in the form of heat. This heat is used to boil water and produce steam, which drives turbines to generate electricity.
An atom whose nucleus decays over time is called radioactive. Some examples of radioactive substances are uranium, plutonium, and einsteinium.
During radioactive decays heat is released.
During radioactive decays heat is released and the center of the Earth is melted.
