Answer
To determine which statement best describes the samples, let's analyze the information given in the table step by step:Step 1: Understand the given information.The table lists four samples, each with the same number of protons (36) but different numbers of neutrons (44, 46, 48, and 50).Step 2: Recall the definitions of the terms in the answer choices.- Chemical properties of an element are determined by the number of protons, which is the atomic number.- The atomic number is the number of protons in the nucleus of an atom.- Allotropes are different structural forms of the same element in the same physical state.- Isotopes are atoms of the same element (same number of protons) that have different numbers of neutrons and therefore different mass numbers.Step 3: Evaluate the answer choices.A. The chemical properties are different for each element.This statement is incorrect because the chemical properties of an element are determined by the number of protons, which is the same (36) for all samples.B. The atomic number is different for each element.This statement is incorrect because the atomic number, which is the number of protons, is the same (36) for all samples.C. They are allotropes of the same element.This statement is incorrect because allotropes refer to different structural forms of the same element, not differences in neutron numbers.D. They are isotopes of the same element.This statement is correct because all samples have the same number of protons but different numbers of neutrons, which is the definition of isotopes.Step 4: Select the correct answer.The correct answer is D. They are isotopes of the same element.Final Answer: D. They are isotopes of the same element.
