Hydrogen has one very rare radioactive isotope: hydrogen-3, commonly known as tritium; also some artificial radioactive isotopes as 4H, 5H, 6H.
An element can be radioactive regardless of its number of protons. Radioactivity depends on the specific isotopes of an element, which can have different numbers of neutrons. Elements with unstable isotopes that undergo radioactive decay typically have too few or too many neutrons compared to the number of protons.
Not always -- Hydrogen-3 is radioactive, for example.
The initial dollar store franchise fee is about $20,000. Other fees (including leaseholds, equipment, shelving, inventory and support) will amount to between $100,000-$600,000 depending on the size and location of the store.
The lightest "element" that can undergo radioactive decay is the isotope hydrogen-3, which undergoes beta decay. The lightest element with no radioactively stable isotopes is technetium, and its isotopes have different modes of decay.
Uranium, boron, hydrogen are chemical elements. Salt (NaCl) is a chemical compound.
non radioactive element
Hydrogen is not naturally radioactive. It is the simplest and most abundant element in the universe, made up of one proton and one electron. However, under certain conditions, hydrogen can be made radioactive through artificial processes, such as bombarding it with high-energy particles in a laboratory setting.
The element with the lowest atomic number is hydrogen.
Hydrogen is an element.
The simplest chemical element is hydrogen.
There are at least 50 different elements produced in a nuclear explosion, most are fission products in 2 peaks, some are formed by neutron capture and beta decay. The majority of these are radioactive isotopes of the elements.
Radium was the radioactive element that was mixed with zinc sulfide to make glow-in-the-dark paint for wristbands.
