Isotopes of an element have the same chemical properties because they have the same
A.electron configuration
B.mass number
C.number of neutrons
D.density
Explanation
Core Concept
Chemistry is governed by electrons, and isotopes differ only in neutrons. Identical electron configurations give identical bonding behavior, though masses (and rate-related properties) differ slightly.
