Asked by wiki @ in Chemistry viewed by 274 People


All isotopes of an element have the same number of neutrons. have the same number of protons. have the same atomic number. have the same mass number. have different chemical properties.

Answered by wiki @


From the given information;

  • all isotopes of an element do not have the same number of neutrons,
  • have the same number of protons
  • have the same atomic number
  • do not have the same mass number
  • have the same chemical properties.

An isotope is are two or more atomic element that contains the same equal number of protons in the nucleus of an atom but with a different number of neutrons.

They share the same similar chemical properties and they behave in the same manner in the chemical reaction but have different mass numbers due to the different number of neutrons.

The difference in their mass numbers influences the rate of their chemical reactions.

They also exhibit different stability. While some are stable, some are unstable, and they can be referred to as radioactive isotopes.

Therefore, we can conclude that:

  • all isotopes of an element do not have the same number of neutrons,
  • have the same number of protons
  • have the same atomic number
  • do not have the same mass number
  • have the same chemical properties.
