Make a brief remark about isotopes.

Solution

Chemical Compounds :

  • A compound is a substance formed by combining two or more chemical elements in such a way that the atoms of the various elements are linked together by chemical bonds that are difficult to break.
  • There are numerous elements in chemistry. Each has its own set of characteristics and composition. The amount of protons, electrons, and neutrons in an element determines its attribute entirely.

Isotopes:

  • Isotopes are elements that have the same atomic number but a different mass number.
  • The presence of a varied number of neutrons in elements with the same atomic number results in isotopes, because the mass number is the sum of the number of neutrons and protons.
  • The term "isotope" refers to a change in an element's atomic mass or weight.
  • Examples :

Carbon:

  • Carbon is made up of three different isotopes: Carbon-12, Carbon-13, and Carbon-14.
  • Carbon-12: It has a total of six neutrons.
  • Carbon-13 is a nucleus with seven neutrons.
  • Carbon-14 has an atomic number of eight neutrons.

Hydrogen:

  • Protium, Deuterium, and Tritium are the three stable isotopes of hydrogen.
  • There are no neutrons in protium.
  • One neutron is found in deuterium.
  • Tritium is a two-neutron element.
