Sodium has no radioactive isotopes.
Radium, by a big margin. Radium has no isotopes that are not radioactive, but no naturally occurring isotopes of potassium or sodium are radioactive.
Sodium chloride is a chemical compound not an isotope. But:- natural sodium contain the rare radioactive isotope 22Na and the stable isotope 23Na- natural chlorine contain the rare radioactive isotope 36Cl and the stable isotopes 35Cl and 37Cl
Sodium does not have naturally occurring radioactive isotopes - as it has only 1 naturally occurring isotope, which has 11 protons and 12 neutrons, and is not radioactive. However, the 18 other known types of sodium isotopes are all radioactive, and sodium-22 (the most stable radioactive sodium isotope) has a half life of 2.6 years.
Three families of elements that contain no radioactive isotopes are the noble gases (such as helium, neon, and argon), the alkali metals (such as lithium, sodium, and potassium), and the alkaline earth metals (such as beryllium, magnesium, and calcium). These families consist of stable elements that do not have any naturally occurring radioactive isotopes.
no
Hydrogen has only one natural radioactive isotope(3H), of cosmogenic origin, but only in ultratraces on the earth. Sodium has two radioactive natural isotopes (22Na and 24Na), of cosmogenic origin, but only in ultratraces on the earth. Oxygen has not natural radioactive isotopes. All the isotopes of uranium are radioactive.
Sodium primarily exists as stable sodium-23, which is the most common and stable isotope of sodium. However, sodium can also form radioactive isotopes, with sodium-22 being a well-known example that is radioactive.
Yes, promethium, which is a lanthanide, has no stable isotopes.
1. Sodium has 20 isotopes and 2 isomers. 2. Only the isotope 23Na is stable. 3. The stable isotope 23Na and the radioactive isotopes 22Na and 24Na (these isotopes exist in traces) are natural isotopes.
Sodium has two natural isotopes: Na-23 (stable) and Na-22 (radioactive, but only in traces).
Not all isotopes are radioactive; the radioactive isotopes are unstable and emit radiations.
Uranium deposits may contain infinitesimal amounts of technetium isotopes.
