In nuclear physics, isotopes of the same element are classified by their atomic structure. If we compare the neutral atoms and the bare nuclei of carbon-12 (612C^{12}_{6}\text{C}612C) and carbon-14 (614C^{14}_{6}\text{C}614C), which of the following statements is correct?
The neutral atoms have different chemical properties due to the difference in their electron configurations.
The bare nuclei have the same specific charge because they belong to the same element and have the same nuclear charge.
The neutral atoms have identical chemical properties, while their bare nuclei have different specific charges due to the different number of neutrons.
The nuclei have different numbers of protons, which results in different chemical bonding behaviors when ionized.
