Ablation turns the material into individual molecules.
Yes, when done perfectly in a lab. Under less than ideal conditions, temperature gradients cause cracks and then flakes are released and expelled.
Drag brings those flakes to the ground.
Flakes of solid material are typically far more than dense than structures made of the same material. Therefore flakes' orbital lifetimes are likely longer than structures made of the same materials.
