    This is a Multiple Choice Questions as classified in NCERT Exemplar

    Answer- (c)

    Explanation- The atomic number of lithium is 3, therefore, the radius of Li+ ion in its ground state, on the basis of Bohr’s model, will be about 1/3 times to that of Bohr radius.

    Therefore, the radius of lithium ion is near 53/3=18≈ pm.
