boron occurs naturally as two isotopes. what is the difference between these isotopes?\nthey have different numbers of electrons and different charges.\nthey have different numbers of neutrons and different charges.\nthey have different numbers of protons and different mass numbers.\nthey have different numbers of neutrons and different mass numbers.
Answer
Brief Explanations:
- Isotope definition: Isotopes are atoms of the same element. Since they are the same element, the number of protons (which determines the element's identity) is the same. For a neutral atom, the number of electrons equals the number of protons, so the number of electrons is also the same, and thus the charge (which is related to the balance of protons and electrons) is the same.
- Mass number formula: The mass number (A = Z + N), where (Z) is the number of protons and (N) is the number of neutrons. Since (Z) is the same (same element) for isotopes, if (N) (number of neutrons) is different, then (A) (mass number) is different.
Answer:
They have different numbers of neutrons and different mass numbers.
