Q. Atomic number of an atom gives the number of which of the following ?
✅ Correct Answer: (B)
Protons
Explanation: The atomic number of an atom represents the number of protons in the nucleus of the atom. Since the number of protons also determines the element's identity on the periodic table, the atomic number is unique to each element. In a neutral atom, the number of electrons will also be equal to the number of protons, but the atomic number specifically refers to the protons.
