One of the primary science goals of the Atacama Large Millimeter Array is to image star forming regions in unprecedented detail and sensitivity. Here, we present BIMA observations of a young embedded stellar group in Serpens that demonstrate some of the issues in this field that ALMA may address in the future. The high resolution of the interferometer enables us to to follow the structure, dynamics, and chemistry of the overall cluster forming cloud down to the scale of individual star forming cores. There is an approximately equal mix of cores with and without continuum sources suggesting that new stars are continually being added to the group. There is evidence for large scale collapse onto the cluster with concentrations toward regions where the velocity dispersion is at a local minimum. There are also significant differences in relative abundances throughout the cluster indicating that molecule formation and depletion timescales are comparable to or less than dynamical timescales for core formation and that chemistry may be used as a signature of their evolution. We discuss a scenario for cluster formation through the condensation and collapse of individual cores via turbulent dissipation and point out a few ways in which ALMA may contribute to future studies.
