What is isotope

noun each of two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei, and hence differ in relative atomic mass but not in chemical properties; in particular, a radioactive form of an element."some elements have only one stable isotope"

What is a isotope simple definition?

Atoms with the same number of protons but different numbers of neutrons are called isotopes. They share almost the same chemical properties, but differ in mass and therefore in physical properties.

What is isotope with example?

The atoms belonging to the same element, having same atomic number Z, but different mass number A, are called isotopes. For example, carbon-12, carbon-13 and carbon-14 are three isotopes of the element carbon with mass numbers 12, 13 and 14 respectively.

What are isotopes Class 11?

Isotopes are defined as the atoms of the same element, having the same atomic number but different mass number. Example: Isotopes of Hydrogen are Protium (Z=1, A=1), Deuterium (Z=1, A=2), Tritium (Z=1, A=3)

What is isotope one word answer?

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.
