What is the heaviest radioactive element?
Polonium is often considered to be the most radioactive element, but there are far more radioactive elements like nobelium and lawrencium. However, the most radioactive elements are man-made like ununtrium and ununseptium. Out of these, ununoctium is the most radioactive but scientists are continuing to make even more radioactive elements today.
Why do some elements not have relative atomic masses eg. radium?
All the elements has an atomic weight; sometimes for the unstable radioactive elements is indicated only the value of the atomic mass of the most stable isotope.The term atomic weight is used for elements and the term atomic mass for isotopes (after the rules and the tradition of IUPAC).
How did radium and polonium get its name?
Radium got its name from the Latin word radius, meaning ray. The early studies of radioactive elements (by Pierre and Marie Curie and others) found that their photographic effects were similar to that of light rays. Scientists categorized the "rays" given off by radioactive elements by their reaction with magnetic fields. Eventually the positive "rays" were named as Alpha particles (helium nuclei). Beta particles were negatively charged (electrons), and Gamma rays had no charge.
Are elements such as Plutonium and Uranium more reactive than Francium?
It's important to note that plutonium and uranium (element names are not normally capitalized in the middle of a sentence) have isotopes which are stable enough that their reactivity is experimentally known, while the most stable isotope of francium has a half-life of about 20 minutes. Francium's reactivity is therefore partially a matter of conjecture... the energy given off by its radioactive decay would literally vaporize any reasonably sized piece. That said, as an alkali metal francium would be much more reactive than uranium or plutonium, both of which are transition metals.
Is radium treatment given everyday?
Today the radiotherapy wit radium is only rarely used; many other isotopes are more cheaper and efficient.
Why is plutonium radioactive?
No it does not. There are various types (isotopes) of plutonium. Plutonium 238, the weapons grade material, has a half life of 88 years. Meaning after 88 years half of the material has transforms into another element through radioactive decay. Plutonium-240 has a half life of ~80 Million years. But eventually all types of plutonium will decay into other elements. All radioactive elements will eventually decay into non-radioactive atoms given enough time.

Are infrared waves given off by plutonium?
No, plutonium does not naturally emit infrared waves. Plutonium is a radioactive element that primarily emits alpha particles, beta particles, and gamma rays as part of its decay process. Infrared waves are part of the electromagnetic spectrum and are typically associated with heat radiation rather than radioactive decay.

If radioactive radium has a half life of approximately 1599 years What percent of a given amount remains after 980 years?
Luckily got it on my last try it was apparently 65.39%
What name is given to elements with an atomic number greater than 92?
They are called the trans-uranic elements. They are either synthetic or the rare product of radioactive decay.
What elements is radioactive and synthetic barrium cesium currium and xenon?
Curium {Note correct spelling} is only element in the list given that is radioactive and synthetic.^ not correct answer and not even spelled right the correct answer is "lawrencium"The rare earth elements are located at the bottom of the periodic table and are comprised of the lanthanoid series and the actinoid series.The actinoid series is the second row of rare earth elements. All of these elements are radioactive, and all of these elements (except actinium, thorium, protactinium, and uranium) are synthetic.
What is the radioactive metal used in nuclear power plants?
Certain radioactive isotopes have an affinity or liking for certain body cells. Thus iodide given to a patient will bunch up and help machines "visualize" the thyroid so that a gland expert doctor can determine if there is something wrong.
Is holmium radioactive?
Holmium actually has the highest magnetic strength out of all known elements given it is first submersed in an artificially produced magnetic field.

When a radioactive elements decays it releases?
Carbon-14 was the answer given; however, through a painful grading experience I found it is wrong. The actual answer is ( Particles and Energy)
