Atoms are mostly empty space. At its center, there is a nucleus which is where the majority of its mass is located. Tiny particles called protons and neutrons make up the nucleus. Protons have a positive electric charge while neutrons don't have any charge. Electrons circle around the nucleus just like all the planets in our solar system orbit orbit around the brightest star in the sky, the sun.
No matter if energy is totally conserved during the fall or when it hits the ground, the kinetic energy of the silver sphere will be zero because the velocity component in becomes zero, the over all energy becomes zero.
