# Why does metallic character decrease along a period?

Feb 9, 2017

$\text{Metallic bonding}$ is characterized by $\text{delocalized electrons}$ that are conceived to be spread out across the metallic lattice, rather than be localized to a particular nucleus.
And such $\text{metallic bonding}$ gives rise to properties such as $\text{malleability}$, and $\text{ductility}$, as well as $\text{electrical conductivity}$, in that the valence electrons are free move between a core of positive charged nuclei.
