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.
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 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.

Isotopes are samples of an element with different numbers of neutrons in their atoms. The number of protons for different isotopes of an element does not change. Not all isotopes are radioactive. Stable isotopes either never decay or else decay very slowly. Radioactive isotopes undergo decay.
Isotopes are atoms that have the same number atomic number, but different mass numbers due to a change in the number of neutrons. The three isotopes of carbon can be referred to as carbon-12 (126 C 6 12 C), carbon-13 (136 C 6 13 C), and carbon-14 (146 C 6 14 C) refers to the nucleus of a given isotope of an element.
The meaning of ISOTOPE is any of two or more species of atoms of a chemical element with the same atomic number and nearly identical chemical behavior but with differing atomic mass or mass number and different physical properties. How to use isotope in a sentence.
Atoms that have the same atomic number (number of protons), but different mass numbers (number of protons and neutrons) are called isotopes. There are naturally occurring isotopes and isotopes that are artificially produced.
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.
These differing atoms of the same element are called isotopes. Four isotopes of helium (He) are shown in Figure 1-1. All atoms of chlorine (Cl) have 17 protons, but there are chlorine isotopes having 15 to 23 neutrons.
