This succulent has a pinkish/purple stems that hang over the pot it is in; the leaves have 10 small points, just on the tips. The leaves are also green and are covered in a white powder coating, giving them a bluish hue.
I'm pretty sure this is one of the Kalanchoe tribe - there are many to choose from, and many share similarities, such as paired opposite leaves, with scallops, or zig-zag edges on the leaves.
This one appears to be Kalanchoe pumila according to Dave's Garden Website, also known as the Flour Dust plant (or spelled as Flower Dust Plant, which makes no sense!).
These plants are reliable, easy to grow and propagate, and in bloom, spectacular.
Frequent pinching will encourage it to be bushier and less trailing, and brighter light may prod it into bloom.
Happy Succulent Growing!
