Question

Isotones have the same number of

• A. Protons
• B. Electrons
• C. Neutrons
• D. All of the above

Hint:

Isotones have the same number of neutrons, while isotopes have the same number of protons.

Answer 1

The Correct Option is C

Step 1: Understanding Isotones
Isotones are nuclei that have the same number of neutrons but a different number of protons.
This means that isotones have the same neutron count but different atomic numbers (protons).
Step 2: Why Other Options are Incorrect
Option (a) is incorrect because isotones do not have the same number of protons; they have a different number of protons.
Option (b) is incorrect because isotones are defined by their neutron number, not by the number of electrons.

Option (d) is incorrect because isotones only share the same number of neutrons, not protons or electrons.

Step 3: Conclusion
Thus, isotones have the same number of neutrons.
