Isotopes
Introduction:
Isotopes are atoms of the same element that have different numbers of neutrons in their nucleus. This means that isotopes have the same atomic number (number of protons) but different mass numbers (sum of protons and neutrons).
Characteristics of Isotopes:
1. Radioactivity: Isotopes of some elements are radioactive, which means they undergo spontaneous radioactive decay and emit radiation. This characteristic is not exhibited by all isotopes, but only by certain elements. Therefore, option a) correctly matches the characteristic of isotopes.
2. Atomic Number: Isotopes are atoms of the same element. This means that they have the same atomic number, which determines the element's identity. Therefore, option b) does not match the characteristics of isotopes because isotopes are not atoms of different elements.
3. Number of Neutrons: Isotopes differ in the number of neutrons they possess. The atomic number remains the same, but the mass number varies due to the different number of neutrons. Therefore, option c) correctly matches the characteristic of isotopes.
4. Chemical Properties: Isotopes have similar chemical properties because they have the same number of protons and electrons, which determine the element's chemical behavior and reactivity. Therefore, option d) correctly matches the characteristic of isotopes.
Conclusion:
Among the given options, option b) does not match the characteristics of isotopes. Isotopes are atoms of the same element with different numbers of neutrons, not atoms of different elements. Isotopes can be radioactive, have different numbers of neutrons, and exhibit similar chemical properties.

Isotopes are members of a family of an element that all have the same number of protons but different numbers of neutrons. The number of protons in a nucleus determines the element's atomic number on the Periodic Table.
