Oxygen-15 and oxygen-13.
Oxygen has two isotopes.
There are three stable isotopes of oxygen that lead having a standard Atomic Mass of 15.9994(3) ,10 unstable isotopes have also been characterized.
The most important isotopes of uranium are 235U and 238U (natural isotopes).
C (98-89%) and G (1-11%)
Hydrogen is not radioactive; its two most common isotopes are stable.
Tellurium is radioactive, though there are stable isotopes. The radioactive isotopes found in nature account for more than two thirds of any normal sample. Additional synthetic radioactive isotopes exist.
Yes, one of its isotopes, tridium, which has an atomic weight of two and an extra two neutrons its its nucleus, is highly radioactive, as well as rare.
Neodymium is radioactive, though for most practical purposes it can be regarded as stable. 30.4% of neodymium is of two radioactive isotopes, but their half lives are very long, the shorter being 2,290,000,000,000,000 years. Like all other elements, neodymium has synthetic radioactive isotopes.
Fluorine has probable a natural radioactive isotope (F-18) but only as traces.Chlorine has a natural radioactive isotope (Cl-36) but only as traces.Bromine hasn't natural radioactive isotopes.Iodine has probable a natural radioactive isotope (I-125) but only as traces.Astatine has only radioactive isotopes.
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.
Hydrogen is not radioactive; its two most common isotopes are stable.
Tellurium is radioactive, though there are stable isotopes. The radioactive isotopes found in nature account for more than two thirds of any normal sample. Additional synthetic radioactive isotopes exist.
Name two radioactive isotopes that are used to irradiate food.
Nitrogen has two stable isotopes: N-14 and N-15 and 14 radioactive isotopes.
Yes, one of its isotopes, tridium, which has an atomic weight of two and an extra two neutrons its its nucleus, is highly radioactive, as well as rare.
Isotopes are atoms of the same element with different numbers of neutrons. Stable isotopes have a balanced number of protons and neutrons, meaning their nuclei do not decay over time. Unstable isotopes, also known as radioactive isotopes, have an imbalance of protons and neutrons, causing their nuclei to decay and emit radiation over time.
Neodymium is radioactive, though for most practical purposes it can be regarded as stable. 30.4% of neodymium is of two radioactive isotopes, but their half lives are very long, the shorter being 2,290,000,000,000,000 years. Like all other elements, neodymium has synthetic radioactive isotopes.

7Li.It is one of the Primordial_elementsor, more properly, primordial isotopes, produced in Big Bang nucleosynthesis. Thus it is more abundant.
Two examples are: carbon-14 and cobalt-60.
