each of two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei, and hence differ in relative Atomic Mass but not in chemical properties; in particular, a radioactive form of an element. Example : carbon12
Isotopes are different versions of an element with varying numbers of neutrons in their nucleus. They have the same number of protons but different numbers of neutrons. These variations in neutrons give each isotope a different atomic mass. Isotopes can be stable or radioactive, and they play a crucial role in various scientific fields like medicine, Archaeology, and environmental studies.

What is the isotop of oxygen?
Oxygen has 3 stable isotops found in the nature 16O (99,757%), 17O (0,038%), 18O (0,205%). There are also 14 other isotops made by humans, but the most stable one is 15O with a half-life of 122 seconds.
Which nuclide is a radioisotope used in the study of organic reaction mechanisms?
Carbon-14 is a common radioisotope used in the study of organic reaction mechanisms. It is used to trace the path of carbon atoms in molecules, allowing chemists to understand how reactions occur and molecules are transformed.
What is Dubnuim?
Dubnium is an element with atomic number 105. marked as Db. Atomic weight (of stable isotop)-268g D-Block Element-Period 7 & group 5. Properties similar to that of other members in group 5. Dubnium is not present in nature but belongs to those elements prepared synthetically in labs. First observed in Russia.
What is the behavior of carbon 12 and carbon 14 in a sugar molecule?
Carbon-12 and carbon-14 behave similarly in a sugar molecule, as they both participate in the chemical reactions of the sugar. However, carbon-14 is radioactive and will decay over time, while carbon-12 is stable. This difference in stability can be used to determine the age of the sample through a process called carbon dating.
Does carbon have larger atoms than fluorine?
Yes, carbon atoms are larger than fluorine atoms. This is because as you move down a group in the periodic table, the atomic size increases due to the addition of more electron shells. Carbon is located in period 2 while fluorine is located in period 3, so carbon has a larger atomic radius.
What are two ways to date fossils?
Two ways to date fossils are relative dating, which involves determining the age of a fossil in relation to other fossils or geological layers, and absolute dating, which provides a numerical age for a fossil using techniques like radiometric dating.
Why is potassium-40 used to date objects older than 50000 years old?
Potassium-40 is used to date objects older than 50,000 years because it has a long half-life of 1.3 billion years, allowing for dating of very old samples. When potassium-40 decays, it turns into argon-40, which can be measured to determine the age of the sample.
What is 201-thallium?
simple meaning. tallium are an metal or isotop that is used as a medical aid.thallium 201 a radioactive isotope of thallium having a half-life of 3.05 days and decaying by electron capture with emission of gamma rays (0.135, 0.167 MeV); it is used as a diagnostic aid in the form of thallous chloride Tl 201.or if you go wikipedia.Thallium is a chemical element with the symbol Tland atomic number 81. This soft gray poor metal resembles tin but discolors when exposed to air. The two chemists William Crookes and Claude-Auguste Lamy discovered thallium independently in 1861 by the newly developed method of flame spectroscopy. Both discovered the new element in residues of sulfuric acid production.Approximately 60-70% of thallium production is used in the electronics industry, and the remainder is used in the pharmaceutical industry and in glass manufacturing.[2] It is also used in infrared detectors. Thallium is highly toxic and was used in rat poisons and insecticides. Its use has been reduced or eliminated in many countries because of its nonselective toxicity. Because of its use for murder, thallium has gained the nicknames "The Poisoner's Poison" and "Inheritance Powder" (alongside arsenic).
