Correct answer: B. Isobars
- A. Isotopes
- B. Isobars
- C. Isotones
- D. Isomers
Explanation
Isotopes: Atoms of the same element with the same number of atomic numbers but a different mass number.Isotones: Species or atoms having the same number of neutrons.Isobars: Atoms having the same mass number but different atomic numbers. Isomers: Compounds have the same molecular formulae but different physical and chemical properties. (n-butane) (Iso-butane)

About Discovery of the Proton
The discovery of the proton follows the study of positive rays, also called canal rays, observed in discharge tubes and later identified as positively charged particles. The work of Goldstein and Rutherford is linked to the proton's charge, relative mass and role in the nuclear model, distinct from the discovery of the electron.
