Which of the following does not match the characteristics of an Isoto...
Explanation:
Isotopes are atoms of the same element that have the same number of protons but differ in the number of neutrons. Here are the characteristics of isotopes:
1. Isotopes of some elements are radioactive:
Some isotopes of certain elements are radioactive, meaning they have unstable nuclei that decay over time, emitting radiation in the process. This characteristic is due to the imbalance between the number of protons and neutrons in the nucleus, leading to an unstable atomic configuration. Radioactive isotopes are used in various applications, including medicine (radiation therapy and diagnostic imaging) and dating archaeological artifacts (carbon dating).
2. Isotopes are the atoms of the same element:
Isotopes are atoms of the same element, meaning they have the same number of protons. For example, carbon-12, carbon-13, and carbon-14 are isotopes of carbon because they all have six protons. However, they differ in the number of neutrons (carbon-12 has 6 neutrons, carbon-13 has 7 neutrons, and carbon-14 has 8 neutrons).
3. Isotopes differ in the number of neutrons:
The main characteristic that distinguishes isotopes is the difference in the number of neutrons. While the number of protons determines the element's identity, the number of neutrons can vary, resulting in different isotopes of the same element. These isotopes may have different physical properties, such as atomic mass and stability.
4. Isotopes have similar chemical properties:
Isotopes of the same element have similar chemical properties because they have the same number of protons and electrons. Chemical reactions primarily involve the electrons in the outermost energy level, known as the valence electrons. Since isotopes have the same number of valence electrons, they tend to exhibit similar chemical behavior and form similar compounds.
Conclusion:
Among the given options, option 'B' does not match the characteristics of an isotope. Isotopes are not atoms of different elements but rather atoms of the same element with different numbers of neutrons.

Elements with the same atomic number but a different mass number are defined as “Isotopes”.
