When describing the isotopes of the same element, the most accurate statement is that they have:
- A
The same atomic number but different atomic masses
- B
The same atomic mass but different atomic numbers
- C
Different numbers of protons and neutrons
- D
Different numbers of electrons
This is the correct answer. Isotopes are atoms of the same element that have the same number of protons (atomic number) but different numbers of neutrons. This difference in neutrons results in different atomic masses.
This is the correct answer. Isotopes are atoms of the same element that have the same number of protons (atomic number) but different numbers of neutrons. This difference in neutrons results in different atomic masses.
This is incorrect. Isotopes cannot have the same atomic mass but different atomic numbers, as the atomic number determines the element itself.
This is incorrect. Isotopes have the same number of protons but different numbers of neutrons.
This is incorrect. In neutral atoms, the number of electrons is equal to the number of protons, so isotopes of the same element will also have the same number of electrons.
