What Is an Isotope? Definition and Examples - Science Notes …
2019年9月13日 · Isotopes are forms of an element that have different numbers of neutrons. All isotopes of an element have the same atomic number and number of protons, but they have different atomic masses from each other. Isotopes of an element share similar chemical properties, but have different nuclear properties. Every element has isotopes.
Isotope | Examples & Definition | Britannica
2024年11月21日 · An isotope is 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 behavior but with different atomic masses and physical properties.
Isotope - Wikipedia
Isotopes are distinct nuclear species (or nuclides) of the same chemical 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 different nucleon numbers (mass numbers) due to different numbers of neutrons in their nuclei.
Isotope Meaning - What are Isotopes? (Definition and …
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. Learn about the meaning of isotopes here.
What are Isotopes? | IAEA - International Atomic Energy Agency
2022年8月19日 · Isotopes are forms of a chemical element with specific properties. Like everything we see in the world, isotopes are a type of atom, the smallest unit of matter that retains all the chemical properties of an element.
Isotopes: Definition, Meaning, Examples, Uses - Scienly
2024年9月22日 · Definition: Atoms of an element which have the same atomic number but different mass numbers are called isotopes of that element. These isotopes are variants of the same element in which the number of protons remains constant, but the neutron count varies. For example, the hydrogen element has three isotopes:
Isotope Basics | NIDC: National Isotope Development Center
What are Isotopes? Atoms are composed of a cloud of electrons surrounding a dense nucleus that is 100,000 times smaller and comprised of protons and neutrons. The number of protons(i.e., atomic number, "Z") determines the element; for example, a strontium nucleus always has 38 protons, and a rubidium nucleus always has 37.
DOE Explains...Isotopes - Department of Energy
Isotopes are members of a family of an element that all have the same number of protons but different numbers of neutrons. The number of protons in a nucleus determines the element’s atomic number on the Periodic Table. For example, carbon has six …
What Is an Isotope? - HowStuffWorks
2023年6月9日 · Isotopes are a vital concept in the study of atoms. Chemists, physicists and geologists use them to make sense of our world. But before we can explain what isotopes are — or why they're so important — we'll need to take a step back and look at atoms as a whole.
Isotopes of Elements - Definition, Types,Examples, Physical and ...
What Is An Isotope? The term “isotope” mainly refers to the variation in the atomic mass or weight of an element. It is also defined as variants of a particular element where these variants will have the same number of protons but differ in the number of neutrons in the atom.
