All the decay chain isotopes are radioactive and toxic (excepting the last member which is non-radioactive but also toxic); you think probably to radium or polonium.
neptunium and plutonium
All isotopes of technetium are radioactive. Technetium is found only in trace quantities in nature, and then usually only in certain ores where it is a product of radioactive decay. All of the technetium used is synthetic.
The chemical formula of sodium bromide is NaBr.
Actinium is a natural chemical element, radioactive; actinium is a decay product of uranium.
Uranium itself is a radioactive and toxic element. All the elements from the decay chain of uranium isotopes are also radioactive (ex.: radon, radium, etc.) excepting the final product, an isotope of lead.
Gold is a metallic element, not a process, therefore no gold does not have a waste product.
xenon is usually a waste product of nuclear reactors and although has power not that much
A daughter product is either a different element altogether, or is a different nuclide of the same parent element. A daughter product may or may not be radioactive. radioactive decay is a nucleus consists of a bunch of protons and neutrons known as nucleons.
The end products of uranium isotopes decay chain are the isotopes of lead.
I assume you mean unuNbium, now officially named Copernicium. It is an extremely radioactive element with atomnumber 112. Based on the atomnumber this element is the product of any successful fusion reaction between elements that add up to this number or the decay of any higher even numbered element. I say even because the emitted radioactive alpha radiation is a hydrogen core consisting of two protons. The decay will then continue to jump over each second element until it reaches a stable non radioactive element.
Only the end product of the decay chain of uranium, a non radioactive isotope of lead.
The daughter isotope is the result of the radioactive disintegration of the parent isotope. For example radium is a product of the uranium disintegration.The two isotopes have different chemical (different atomic numbers, etc.), physical and nuclear properties.
