Final answer:
Isotopes of an element have the same chemical properties and react the same way with other elements because they have identical numbers of electrons; hence, the answer is A. True.
Step-by-step explanation:
Different isotopes of a given element will react the same way with other elements. The correct answer to this question is A. True. Atoms of an element always have the same number of protons but can have varying numbers of neutrons, making them isotopes. These isotopes differ in mass but not in chemical properties because they have the same number of electrons. Chemical reactions depend on the arrangement of electrons, thus isotopes of an element exhibit the same chemical behavior and reactivity. However, their nuclear properties, such as stability, can vary significantly owing to the differences in the number of neutrons. In a typical chemical laboratory setting, different isotopes of an element appear and react the same.
