Isobars are atoms that have:a)The same atomic number but different mas...
Isobars are defined by their mass numbers and atomic numbers.
- Mass Numbers: Isobars have the same mass number.
- Atomic Numbers: They possess different atomic numbers.
This means isobars are atoms with the same total number of protons and neutrons combined but differ in their number of protons (atomic number).

Understanding Isobars
Isobars are a concept in nuclear chemistry that refers to atoms of different elements that share the same mass number but have different atomic numbers. Here's a detailed explanation of isobars:
Definition of Isobars
- Isobars are atoms that have:
- The same mass number (the total number of protons and neutrons).
- Different atomic numbers (the number of protons).
Why Option 'C' is Correct
- In option 'C', the statement emphasizes that isobars have:
- Identical mass numbers, meaning they contain the same total number of nucleons (protons + neutrons).
- Different atomic numbers, indicating that they are different elements.
Examples of Isobars
- A classic example of isobars includes:
- Carbon-14 (6 protons and 8 neutrons) and Nitrogen-14 (7 protons and 7 neutrons).
- Both have a mass number of 14 but differ in their atomic numbers (6 for Carbon and 7 for Nitrogen).
Importance of Isobars
- Understanding isobars is crucial in:
- Nuclear chemistry and physics, where the behavior of elements can be analyzed based on their mass numbers.
- Applications in radiocarbon dating and nuclear medicine, where isotopes play a significant role.
In summary, isobars are fascinating as they reveal how elements can be related through their nucleon count while exhibiting different chemical properties due to their unique atomic numbers.
