Question
Complete the following sentence: 'Different isotopes of the same element have...' 1 pointa) ...the same number of protons, but differing numbers of neutrons and electronsb) ...the same number of neutrons, but differing numbers of protons and electronsc) ...the same number of protons and neutrons, but differing numbers of electronsd) ...the same number of protons and electrons, but differing numbers of neutrons
Solution
The correct answer is d) ...the same number of protons and electrons, but differing numbers of neutrons.
This is because isotopes of an element have the same atomic number, meaning they have the same number of protons. The number of electrons in a neutral atom is also equal to the number of protons. However, isotopes have different numbers of neutrons, which is what makes them isotopes. The number of neutrons in an atom contributes to its atomic mass, so different isotopes of the same element have different atomic masses.
