This work purposes to study the correlation the shape of the isotones that even mass number (A=46-62), and (A= 164-182) with the nuclear charge distribution.

The values of quadruple deformation parameter (β₂) and eccentricity (e) have been calculated as indicator for the varying in the nucleus form and for compare have been plotted the change of the (β₂) and (e) with mass number for the isotones with even mass number (A=46-62), and (A= 164-182).

The value of (β₂) have been calculated by dependence on value of "quadruple transition probability B (E2)", while the value of (e) computed by dependence on the values of "the minor (a) and major (b)". The values of (a&b) calculated by dependence on values of the "mean-squared charge distribution radius average (< r² >) ", quadruple deformation parameter (δ) and electric quadrupole moment (Q₀).

Three dimension (3D) have been plotted for the isotones with even mass number (A=46-62), and (A= 164-182) for identify the change in forms of nucleus by dependence on the values of (a&b).
