Question

Which of these have the same chemical properties, but their physical properties may be different?

• A. Atomic number
• B. Mass number
• C. Isotopes
• D. Isobars

Answer 1

Answer: (C)

Isotopes

Isotopes have same chemical properties, but their physical properties might be different.

Chemical properties of an element depend on its atomic number or number of protons. Isotopes of an element have the same atomic number, hence their chemical properties are the same. But their physical properties may vary.
