Answer:
protons in the atom.
Explanation:
The identity of an element relies on the number of protons in its atom. This is called the atomic number. The atomic number is the basis of the periodic table of elements. Modern periodic law states that "the properties of elements are a periodic function of their atomic number".
Atomic number of atoms do not change and they are convieniently used in identifying an atom.

The dye molecules move in a directed way from high to low concentration
Explanation:
The statement that best describes the motion of dye molecule in water is directed from a region of high to low concentration. The motion of the particles of the dye in water is described as diffusion:
- diffusion is the movement of molecules of a substance from one position to another.
- diffusion occurs from a region of high concentration to that of a low concentration.
- the dye in the water solution causes an increase in concentration of an area where it is dropped.
- this causes the particles to spread outward in the solution.
- a concentration gradient is set up between the two parts of the solution.
- this gradient facilitates the movement of the dye particles.
