Subjective Type

Which of the following has greater atomic size and why? $$y, y^{+1}, y^{-1}, y^{+2}, y^{-2}$$ Arrange them in ascending order of the atomic size.

Solution

$$y^{-2}$$' has greater atomic size. Because here electrons are more than protons. The electrons exceed the influence of nuclear change and become free. This increases the size. Order of sizes is:
$$y^{+2} $$< $$y^{+1}$$< y < $$y^{-1} $$< $$y^{-2} $$.
Ascending order of atomic size is:
$$y^{+2} $$< $$y^{+1}$$<$$y$$ < $$y^{-1} $$< $$y^{-2} $$.
