The link between atoms remain unchanged.
The bonds between hydrogen and oxygen atoms of individual water molecules do not change when liquid water changes to ice. This is a physical change called freezing, and does not cause any chemical changes to occur. Only chemical changes can cause changes in chemical bonds.
The molecule remain unchanged.
Neutral atoms are not identical to ions.
A chemical change.
The kind of change described is referred to as a physical change. Examples of physical changes include, but are not limited to, changing the temperature or state of a substance, changing the shape of a substance, and breaking a substance into smaller pieces. A change that alters a material's composition would be classified as a chemical change.

It is a physical change because only the phase of the salt actually changes - the two compounds do not react. The salt dissolves in the water, but if the water evaporates, the salt is left behind in its solid state.
It does change. Check Table 2 in the related link.

Molecules are composed of two or more atoms linked together. The attractive forces that link these atoms together are called chemical bonds. The same idea is with forces , except on a larger scale. Forces link MOLECULES to MOLECULES. Bonds link ATOMS to ATOMS.
