Question

Make a brief remark about isotopes.

Answer 1

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.
