We present new results concerning the radial gradients (Fe, alpha, s- and r-process elements) 
across the Galactic thin disk. We use young (classical Cepheids) stellar tracers for which 
we collected high resolution spectra with UVES at VLT together with similar estimates 
available in the literature. The investigated elements display well defined negative gradients 
when moving from the innermost to the outermost regions.
Moreover, we also found that the radial gradients of the neutron capture elements are positive 
as a function of age (pulsation period). Thus suggesting an age dependence similar to 
alpha-elements. On the other hand, the slopes of [element/Fe] vs Galactocentric distance are 
more positive than for alpha-elements. We discuss plausible working hypotheses to take account 
of the difference, and perform a detailed comparison with similar abundances for dwarf and giant 
stars available in the literature. Finally, we discuss the abundance ratio between s- and r-process 
elements (La/Eu) and between heavy and light s-process elements (La/Y) and outline their impact on 
the chemical enrichment history of the Galactic thin disk.
