What structural feature is different in isotopes of a particular element?

Short Answer

Expert verified
The structural feature that makes isotopes of a particular element different is the number of neutrons in the nucleus.

Step by step solution

01

Defining Elements and Isotopes

All atoms of a particular element have the same number of protons in the nucleus. Isotopes are varieties of the same element with different numbers of neutrons.
02

Distinguishing Isotopes

Since isotopes vary in the number of neutrons, but not the number of protons, they aren't identical to the base element, but rather variants. They possess the same atomic number (due to the consistent number of protons), but have varying atomic weights because of the differing number of neutrons.
03

Conclusion

Therefore, the structural feature that differentiates isotopes of a particular element is the number of neutrons in the nucleus. Isotopes of an element have the same number of protons but different numbers of neutrons.
