Isotope Definition and Examples in Chemistry - ThoughtCo
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 … WebbIsotopes are primarily represented in two different ways: By writing the name of the element followed by a hyphen and the mass number of the isotope. For example, … Webb5 okt. 2024 · 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 … small tower storage
