Option 4 is correct, i.e. Francium.
- Among the given elements Francium is the highest atomic number which is 87.
Extra facts:
- Henry Moseley classified elements based on Atomic numbers.
- In 1913 A.D. the English scientist Henry Moseley demonstrated, with the help of the experiments done using an X-ray tube, that the atomic number (Z) of an element corresponds to the positive charge on the nucleus or the number of protons in the nucleus of the atom of that element.
- This revealed that ‘atomic number’ is a more fundamental property of an element than its atomic mass.
