You can control the bounciness using the Physics Material2D, you are not using nay for now.

Bets is to create a new one with right-click->create->PhysicsMaterial2D then you are given 2 values only Friction and Bounciness and they do exactly what they say. Then add it to your Collider and you will see differences.

Best is to create one for the ball and one for the ground, the engine will take care of the rest.
