the atoms will begin to giggle around more as they gain thermal energy.

The intermolecular forces are weakened.
As a substance melts, the molecules of the formerly-solid substance becomes less structured and drifts further apart.
When a substance melts, the molecules move more freely and when it freezes, they move more slowly. When a substance boils and becomes a vapor (gas), the molecules again move faster than when in the liquid state, and when the vapor condenses, the molecules move slower.

It's vibrates and then melts
A rock, or any solid substance melts, it becomes less dense due to the heat exciting the molecules. They start to move and are bumping into each other at rapid rates, causing the fluid nature of the melted substance.
Nothing. Melting is a physical change and does not alter the chemical composition of a substance.
An atom itself does not melt. The substance made out of atoms melts when it gets to hot in temperature, and the increased energy in the atoms causes the substance to fall apart somewhat.

The molecules are moving (just) fast enough to break the bonds that was holding the substance into a crystalline (or quasicyrstalline) form.
ice melts because the atoms inside them are stuck together and when it gets hot the atoms separate and the molecules(atoms) then become water vapour
A substance changes from a solid to a liquid at the substance's melting point. This is a different temperature for every substance. For example, water (ice) melts at 0oC, whereas gold melts at 1,064oC.
