yes. eg carbon 14 uranium 238 etc
Naturally occurring radioactive isotopes were created by one or more of the following processes:
Francium is a highly radioactive and unstable element that is never found in its pure form in nature. If it were to be touched, it would likely react explosively with water or air. Due to its extreme rarity and radioactivity, no one has ever touched or felt francium.
Nitrogen atoms do not spontaneously change into other kinds of atoms. However, in nuclear reactions or processes like radioactive decay, nitrogen atoms can be converted into different atoms.
Yes, "Do you ever feel like a plastic bag?" is a simile. It compares feeling emotionally overwhelmed or insignificant to the light and easily tossed around nature of a plastic bag.
Sodium is a highly reactive element and is typically found in nature combined with other elements such as chlorine in salt deposits or in compounds like sodium hydroxide. It is rarely found in its pure form because it readily reacts with air and water.
The heaviest natural radioactive element is Uranium.Man made elements are continuously being made. The latest heaviest superheavyweight man made element to be discovered is element 117 (it is still so new that it hasn't been given a name yet).A little different bit of information about Fermium, a team has captured a piece of its spectrum-the wavelengths of light it absorbs-making it the heaviest element ever to be so measured. It was made in the 1952 detonation of the first thermonuclear bomb. It does not make it as the heaviest element, just the heaviest to have it's light spectrum captured.
Radio activity never stops. Radioactive material emits radioactive rays for ever. How ever it can be capped but when ever the material is exposed it will start emitting gamma and Beta rays.
Yup. It will run out cos it is non renewable
Well, to start with, that is a provisional name, and not the final name. It is a man made substance that does not exist in nature, only about 100 atoms of it have ever been made, it is radioactive, and very unstable- it changes to another material in a fraction of a second.
is hydrogen uncombined in nature
Yes, the Earth's core is slowly cooling down over time, but this process takes billions of years. The heat generated from the radioactive decay of elements in the core keeps it molten, and the heat loss is very gradual. It is not something that will happen in the near future.
No
No
No.
No, it doesn't.
no. The most commonly used radioactive material is Americium
He already came and best concert ever
No.
