1. isotopeverb

   To define or demonstrate an isotopy of (one map with another).

2. Etymology: Coined in 1914 by British chemist Frederick Soddy from ἴσος and τόπος, because the different isotopes of a chemical element always occupy the same position in the periodic table of elements. Compare the synonymous Icelandic word samsæta.

1. Isotope

   Isotopes are distinct nuclear species (or nuclides, as technical term) of the same element. They have the same atomic number (number of protons in their nuclei) and position in the periodic table (and hence belong to the same chemical element), but differ in nucleon numbers (mass numbers) due to different numbers of neutrons in their nuclei. While all isotopes of a given element have almost the same chemical properties, they have different atomic masses and physical properties.The term isotope is formed from the Greek roots isos (ἴσος "equal") and topos (τόπος "place"), meaning "the same place"; thus, the meaning behind the name is that different isotopes of a single element occupy the same position on the periodic table. It was coined by Scottish doctor and writer Margaret Todd in 1913 in a suggestion to the British chemist Frederick Soddy.The number of protons within the atom's nucleus is called its atomic number and is equal to the number of electrons in the neutral (non-ionized) atom. Each atomic number identifies a specific element, but not the isotope; an atom of a given element may have a wide range in its number of neutrons. 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. The atomic number of carbon is 6, which means that every carbon atom has 6 protons so that the neutron numbers of these isotopes are 6, 7, and 8 respectively.

1. isotope

   An isotope is a variant of a particular chemical element, which shares the same number of protons but has a different number of neutrons in its nucleus. This leads to a difference in atomic mass but not in chemical properties. Isotopes can be either stable or unstable; unstable isotopes, also known as radioactive isotopes, emit radiation as they decay over time.

1. Isotope

   Isotopes are variants of a particular chemical element: while all isotopes of a given element share the same number of protons and electrons, each isotope differs from the others in its number of neutrons. The term isotope is formed from the Greek roots isos and topos. Hence: "the same place," meaning that different isotopes of a single element occupy the same position on the periodic table. The number of protons within the atom's nucleus uniquely identifies an element, but a given element may in principle have any number of neutrons. The number of nucleons in the nucleus is the 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. The atomic number of carbon is 6, which means that every carbon atom has 6 protons, so that the neutron numbers of these isotopes are 6, 7 and 8 respectively.

Examples of isotope in a Sentence

1. Brian Fields:

   When you see green bananas in Illinois, you know they are fresh, and you know they did not grow here, like bananas, Pu-244 and Sm-146 decay over time. So if we find these radioisotopes on Earth today, we know they are fresh and not from here -- the green bananas of the isotope world -- and thus the smoking guns of a nearby supernova.

2. Nicolaus Seefeld:

   Unfortunately, it was not possible to examine the strontium isotope ratio of the remaining individuals, because the teeth were too decayed and the result would have been distorted.

3. Kelly Knudson:

   The nitrogen isotope is really good at reflecting seafood consumption, which is interesting to us, because these people were living on the Peruvian coast and had access to one of the richest fisheries in the world. But we didn't know how much of that they were using.

4. Ashleigh Haruda:

   The bones don't just tell us what animal it was, but also tell us a number of other things, such as its ancestry( through ancient DNA) and its diet( through chemical isotope analysis).
