  Supernova remnants (SNRs) offer the means to study supernovae (SNe) long
after the original explosion and can provide a unique insight into the
mechanism that governs these energetic events. In this work, we examine the
morphologies of X-ray emission from different elements found in the youngest
known core-collapse (CC) SNR in the Milky Way, Cassiopeia A. The heaviest
elements exhibit the highest levels of asymmetry, which we relate to the
burning process that created the elements and their proximity to the center of
explosion. Our findings support recent model predictions that the material
closest to the source of explosion will reflect the asymmetries inherent to the
SN mechanism. Additionally, we find that the heaviest elements are moving more
directly opposed to the neutron star (NS) than the lighter elements. This
result is consistent with NS kicks arising from ejecta asymmetries.
