Something that is radioactive is called a radionuclide.
No, it's called "radioactive." "Retroactive" is something that's active in regards to the past.
Hydrogen is an element.
For an object to be considered radioactive, it must contain unstable atoms that undergo radioactive decay, emitting radiation in the process. Common radioactive elements include uranium, thorium, and radium. The level of radioactivity is measured by the rate at which the atoms decay, typically expressed in units such as becquerels or curies.
You can detect radioactivity using a Geiger counter or other radiation detectors. Radioactive materials emit ionizing radiation such as alpha, beta, or gamma particles, which can be measured to determine the level of radioactivity. Additionally, certain properties like half-life and decay products can also indicate if a substance is radioactive.
Biologically it is the lumen.
There are no radioactive spiders. This is something from a movie, and has never happened. There is no way to find images of radioactive spiders.
You can just put something in the sentence that is going to be radioactive that's all.
its nuclei can split apart
Radioactive isotope, or radioisotope.
it is unstable and decays to another element
No. There is no reason why rabbit feces should be radioactive, unless of course they ate something radioactive or they are under medical care using radioactive isotopes. It might be possible that if the soil is radioactive, and the plants become radioactive, that a rabbit might excrete radioactive feces from eating the plants.
Decay Series
Yes some things that are radioactive are toxic. Being able to harm an exposed organism.
Uranium and ummm something else
call poision controll or police
An atom whose nucleus decays over time is called radioactive. Some examples of radioactive substances are uranium, plutonium, and einsteinium.
You grow an extra limb or two.
