Q. The chemical bahaviour of an atom depends upon
✅ Correct Answer: (C)
The number of electrons orbiting around the nucleus
Explanation: The chemical behavior of an atom depends primarily on the number of electrons in its outermost shell (also known as the valence electrons). These electrons are involved in chemical bonding and interactions with other atoms. The number of protons determines the element's identity, and the number of neutrons affects the isotope, but it is the electrons that dictate how an atom behaves chemically.
