∙ 13y agoOxygen has two isotopes.
- Ozone, O3, which is a poisonous gas that exists as a layer in the stratosphere protects the Earth from too much harmful radiation. The ozone layer can be destroyed by particulate matter in the atmosphere. Chloroflurocarbons have been banned in an attempt to protect the ozone layer. Ironically the ice crystals in the Antarctic region also lead to degradation of this layer. Ozone is used to disinfect Swimming Pools.
- Oxygen, O2, is a diatomic ga that makes up approximately 21% of the Earth's atmosphere. It supports combustion and is used by animals and plants in the process of respiration.

How radioactive is hydrogen?
Hydrogen is not radioactive; its two most common isotopes are stable.
Is tellurium radioactive?
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.
Can hydrogen be radioactive?
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.
Is neodymium radioactive?
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.
Is bromine radioactive?
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.
Ion of sodium isotope of uranium proton of hydrogen or proton of oxygen is most likely to be radioactive?
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.

What are two radioactive isotopes that are used to irradiate food?
Name two radioactive isotopes that are used to irradiate food.
What are three different isotopes in nitrogen?
Nitrogen has two stable isotopes: N-14 and N-15 and 14 radioactive isotopes.
Can hydrogen be radioactive?
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.
What is the meaninq of two isotopes stable and unstable isotopes?
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.
Is neodymium radioactive?
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.

What is the most abundant isotope of Lithium?
7Li.It is one of the Primordial_elementsor, more properly, primordial isotopes, produced in Big Bang nucleosynthesis. Thus it is more abundant.
What are 2 radioactive isotopes that make them useful?
Two examples are: carbon-14 and cobalt-60.
Give two examples of how tracers are used tell why radioactive isotopes work as tracers?
Alloys
