Quick Answer: What Do Isotopes Mean?

What best describes an isotope?

any of two or more forms of a chemical element, having the same number of protons in the nucleus, or the same atomic number, but having different numbers of neutrons in the nucleus, or different atomic weights.

Isotopes of a single element possess almost identical properties..

What is the opposite of isotopes?

There are no categorical antonyms for isotope. The noun isotope is defined as: Any of two or more forms of an element where the atoms have the same number of protons, but a different number of neutrons within their nuclei.

How do you use isotope in a sentence?

Isotope in a Sentence 🔉Just like an isotope, you are unlike your sibling because of the differences in your chemical makeups. … An isotope is one of the various types of an element. … While each isotope of an element has an identical proton count, the isotopes do not share the same number of neutrons.More items…

What do isotopes tell us?

Isotopes of an element share the same number of protons but have different numbers of neutrons. … Chemically, all three are indistinguishable, because the number of electrons in each of these three isotopes is the same. So different isotopes of the same element are identical, chemically speaking.

What is isotopes explain with example?

Isotopes can be defined as the variants of chemical elements that possess the same number of protons and electrons, but a different number of neutrons. … For example, uranium-235 and uranium-239 are two different isotopes of the element uranium.

What are isotopes and its uses?

Radioactive isotopes find uses in agriculture, food industry, pest control, archeology and medicine. Radiocarbon dating, which measures the age of carbon-bearing items, uses a radioactive isotope known as carbon-14. In medicine, gamma rays emitted by radioactive elements are used to detect tumors inside the human body.

Why are stable isotopes important?

Stable isotopes have helped uncover migratory routes, trophic levels, and the geographic origin of migratory animals. They can be used on land as well as in the ocean and have revolutionized how researchers study animal movement.

What is another word for isotope?

What are 3 uses of radioactive isotopes?

The most widely used radioactive pharmaceutical for diagnostic studies in nuclear medicine. Different chemical forms are used for brain, bone, liver, spleen and kidney imaging and also for blood flow studies. Used to locate leaks in industrial pipe lines…and in oil well studies.

What are the 2 types of isotopes?

Isotope Facts All elements have isotopes. There are two main types of isotopes: stable and unstable (radioactive). There are 254 known stable isotopes.

How can isotopes benefit humans?

Radioactive isotopes have many useful applications. In medicine, for example, cobalt-60 is extensively employed as a radiation source to arrest the development of cancer. Other radioactive isotopes are used as tracers for diagnostic purposes as well as in research on metabolic processes.

What are the applications of isotopes Class 9?

Uses of Isotopes: Even fossil’s age can be determined by using this technology. An isotope of uranium is used as fuel in nuclear reactor. An isotope of cobalt is used in treatment of cancer. An isotope of iodine is used in treatment of goitre.

What is an isotope easy definition?

Isotope, one of two or more species of atoms of a chemical element with the same atomic number and position in the periodic table and nearly identical chemical behaviour but with different atomic masses and physical properties.

What are 2 examples of isotopes?

Examples of Isotopes:Carbon-14. A naturally occurring radioactive isotope of carbon having six protons and eight neutrons in the nucleus. … Iodine-131. It is an isotope because it contains a different number of neutrons from the element iodine. … Tritium.

How are isotopes harmful?

Isotopes that are not radioactive are called “stable” isotopes. During radioactive decay, a radioactive isotope gives off some type of radiation. … Radioactive isotopes can be dangerous to living things. They can also cause damage to equipment such as electronics.

What causes isotopes to form?

Isotopes can either form spontaneously (naturally) through radioactive decay of a nucleus (i.e., emission of energy in the form of alpha particles, beta particles, neutrons, and photons) or artificially by bombarding a stable nucleus with charged particles via accelerators or neutrons in a nuclear reactors.

How do you determine isotopes?

Isotopes are simply specifying the number of neutrons and protons (together called nucleons) in the atom. So, Carbon-12, which has an atomic mass number of 12, has 6 neutrons (12 nucleons – 6 protons = 6 neutrons).

What are 3 examples of isotopes?

The number of nucleons (both protons and neutrons) in the nucleus is the atom’s mass number, and each isotope of a given element has a different mass number. For example, carbon-12, carbon-13, and carbon-14 are three isotopes of the element carbon with mass numbers 12, 13, and 14, respectively.

How are isotopes important?

Isotopes of an element all have the same chemical behavior, but the unstable isotopes undergo spontaneous decay during which they emit radiation and achieve a stable state. This property of radioisotopes is useful in food preservation, archaeological dating of artifacts and medical diagnosis and treatment.
