which of the following best describes isotopes of an element?\natoms with the same number of neutrons but different numbers of protons\natoms that have the same mass number but different atomic numbers\natoms with the same number of protons but different numbers of neutrons\natoms with different numbers of protons and electrons
Answer
Brief Explanations:
Isotopes are defined as atoms of the same element that have the same number of protons (which determines the element's identity) but different numbers of neutrons, resulting in different mass - numbers.
Answer:
Atoms with the same number of protons but different numbers of neutrons
