Solution
Solution Steps
Step 1: Understanding Isotopes
Isotopes are variants of a particular chemical element that have the same number of protons but different numbers of neutrons. This means that while the atomic number (number of protons) remains the same, the mass number (sum of protons and neutrons) varies.
Step 2: Analyzing the Options
Atomic number: Isotopes of an element have the same atomic number.
Number of protons: Isotopes have the same number of protons.
Number of electrons: In a neutral atom, the number of electrons equals the number of protons, so isotopes of an element have the same number of electrons.
Number of neutrons: Isotopes differ in the number of neutrons.
Number of protons and neutrons: Isotopes have the same number of protons but different numbers of neutrons.
Number of protons, neutrons, and electrons: Isotopes have the same number of protons and electrons but different numbers of neutrons.
