Carbon-12 (612C^{12}_{6}\text{C}612C) and carbon-14 (614C^{14}_{6}\text{C}614C) are two isotopes of carbon.
Which of the following statements correctly compares their chemical properties and the specific charges of their bare nuclei?
They have identical chemical properties because they have the same number of protons, but the bare nucleus of carbon-12 has a larger specific charge than that of carbon-14.
They have different chemical properties because they have different numbers of neutrons, but the bare nucleus of carbon-12 has a smaller specific charge than that of carbon-14.
They have identical chemical properties because they have the same nuclear mass, and their bare nuclei have identical specific charges.
They have different chemical properties because they have different proton numbers, but their bare nuclei have identical specific charges.
