H3, Deuterium is radioactive.
Uranium and plutonium are radioactive and are used in atomic bombs.
pH=-log(H+)
A radioactive tracer is a radioactive atom inserted in a compound to see what happens to it in a reaction, usually in biotechnology. For example, to find out where carbon atoms go in photosynthesis, scientists can give the plants carbon dioxide with carbon-14 instead of carbon-12 and track the progress of the carbon-14.

nope
a solute is a disolveable substance, for example- salt, which can disvile in a SOLVENT, like water. other solutes include sugar and coffee
Lead is most commonly used for protecting people from radioactive substances.For example, if you go to the dentist and they give you an X-ray of your teeth, they will usually give you a lead bib to protect you from the radiation produced by the X-ray. However, carbon (graphite usually) can also be used to shield, but whereas a plate of lead may work it would take a brick of graphite.
Insulin, is an organic substance and is needed in humans for the absorbtion of sugars.
An adsorbent is a substance that sits on top of a solution, instead of dissolving into it. An example of this type of substance is the silica gel that comes in certain products you buy.
Radionuclide or radioisotope is a substance that give off high energy particles or rays as it disintegrates. They emit three types of radioactivity is alpha particles, beta particles, and gamma rays.
Ethene and ethyne.
