The answer is Radium Ra group IIA or atomic number 88
No, copper is a metallic element and is not alive. It is a naturally occurring element found in the Earth's crust.
Plutonium is a non-renewable resource. It is a radioactive element that is primarily produced through the nuclear fission of uranium-238 in nuclear reactors. Once plutonium is used in nuclear reactions, it undergoes a series of radioactive decays and eventually becomes unusable for energy production. Due to the limited availability of uranium-238 and the complex process required to produce plutonium, it is considered a finite and non-renewable resource.
Transmutation is the process by which one element changes into another. This can only be done with a nuclear reaction, but alchemists once believed it might be possible, for example, to transmute lead into gold. They tried many bizarre things, but were never successful. Only nuclear reactions, such as fusion, fission, radioactive decay, etc, can induce a transmutation.
Black is a primary color so you cannot really make it with any other colors.
No, paraffin is not an element. To be an element, a substance must have all the same type of atom. Once it has this, it can go on the Periodic Table. So, as paraffin has many different types of atom in it, it's not an element.
In order for an atom of an element that is not radioactive to become radioactive, the isotope has to change. This can happen as a result of neutron capture. Neutron capture can simply change the isotope of an atom, as when cobalt-59, which is not radioactive, captures a neutron to become cobalt-60, which is radioactive. Neutron capture can also result in immediate radioactive decay of the atom struck, even if it is not radioactive. For example helium-3 can capture a neutron to produce two atoms of hydrogen, one of hydrogen-3 and one of hydrogen-1.
Once latex paint is frozen, it is no good.
No. Once latex paint has frozen, it is ruined.
Yes, you can paint unheated clay and once you heat it, the clay's paint should still stay on.
Once in Paris, once in Auvers.
No, intracavitary radiation does not make people radioactive. The radioactive source used for treatment is placed inside the body temporarily, and once the treatment is completed, the source is removed. The patient does not become radioactive from this procedure.
Because paint pots are basically made out of mud or clay and then you paint them once they harden.
No, the paintbrush can only be used once.
No, once oil based paint has dried, it is not a conductor of electricity.
Once the paint is dry, it shouldn't smudge or run, if it did, the paint wasn't dry. (Fabric Paint, is just like enamel paint, it just has extra ingredients in the paint so it can be washed)
From my personal experience I have seen mustard destroy car paint once it dried.
Once opened, wall paint typically lasts for about 2-3 years if stored properly in a cool, dry place and sealed tightly.
