False. Not all living things on Earth are radioactive. Radioactivity is a natural process that can be found in some elements and materials, but it does not apply to all living organisms.
No: Iodine is not a metal at all, but a nonmetal. It is not necessarily radioactive, but has some radioactive isotopes.
Yes. Things like soil and coffee have an ingredient in them which makes them radioactive meaning they give off radiation. Bananas are also radioactive but there is nothing to panic about - low levels like the ones found in these objects are fine. Your body can handle them.
92.66% of the germanium found in nature is not radioactive. 7.44% of germanium is 76Ge, which has a very long half life of 1.78 x 1021 years.
It depends on the isotope, of which carbon has three that occur naturally. Carbon-12 (about 99%) and carbon-13 (about 1%) are not radioactive; carbon-14 (trace amounts, maybe one part per trillion) is radioactive (beta decay into nitrogen-14) with a half-life of about 5700 years.
Yes some things that are radioactive are toxic. Being able to harm an exposed organism.
Radioactive substances are the things that put off radiation. These could be radioactive waste, or even radioactive materials not yet used.
Radioactive materials can emit radiation which can interact with nearby molecules, causing them to emit light. This phenomenon is known as Cherenkov radiation and is responsible for the glowing effect seen in some radioactive substances.
A radioactive element is an element that emits radiation due to instability. They are commercially used in the generation of electricity in nuclear power plants and home smoke detectors among other things.
Some isotopes are radioactive, some are not.
Stars seem to be, but they don't have big and/or unstable atoms such as most radioactive elements have. They release sub atomic units when their atoms fuse, along with rays such as gamma rays, which is why they can seem to be similar to other radioactive things. Some planets with atmostpheres that are ionised by ionising rays can also be similar to radioactive things perhaps.
False. Not all living things on Earth are radioactive. Radioactivity is a natural process that can be found in some elements and materials, but it does not apply to all living organisms.
No. All things are radioactive, including living things and even humans. All matter (save a few) emits gamma radiation spontaneously.

Polonium is extremely radioactive.
Not all of the transition elements are radioactive. Many of them are, and some of them have common radioactive isotopes, but some of them have no naturally occurring radioactive isotopes. Please note that all elements have synthetic radioactive isotopes, at least.
Some examples are deuterium and tritium which are radioactive isotopes of hydrogen.
