Questions & Step-by-Step Solutions
Which of the following is a characteristic of isotopes?
Step 1: Understand what an isotope is. An isotope is a version of an element.
Step 2: Know that all isotopes of an element have the same number of protons. Protons determine the element's identity.
Step 3: Learn that isotopes differ in the number of neutrons. Neutrons are particles in the nucleus that do not affect the element's identity but change its mass.
Step 4: Conclude that because isotopes have the same number of protons but different numbers of neutrons, they have different atomic masses.
