  We have systematically studied the surface properties, such as symmetric
energy, neutron pressure, and symmetry energy curvature coefficient for Ne, Na,
Mg, Al, and Si nuclei from the proton to neutron drip-lines. The Coherent
Density Fluctuation Model (CDFM) is used to estimate these quantities taking
the relativistic mean-field densities as inputs. The Br\"uckner energy density
functional is taken for the nuclear matter binding energy and local density
approximation is applied for its conversion to coordinate space. The symmetry
energy again decomposed to the volume and surface components within the liquid
drop model formalism to the volume and surface parts separately. Before
calculating the surface properties of finite nuclei, the calculated bulk
properties are compared with the experimental data, whenever available. The
NL3* parameter set with the BCS pairing approach in an axially deformed
frame-work is used to take care of the pairing correlation when needed. The
deformed density is converted to its spherical equivalent with a two Gaussian
fitting, which is used as an input for the calculation of weight function in
the CDFM approximation. With the help of the symmetric energy for the recently
isotopes $^{29}$F, $^{28}$Ne, $^{29,30}$Na and $^{31,35,36}$Mg are considered
to be within the {\it island of inversion} emphasized {\bf [Phys. Lett. B 772,
529 (2017)]}. Although we get large symmetric energies corresponding to a few
neutron numbers for this isotopic chain as expected, an irregular trend appears
for all these considered nuclei. The possible reason behind this abnormal
behavior of symmetry energy for these lighter mass nuclei is also included in
the discussion, which gives a direction for future analysis.
