The Rutherford–Bohr model of the hydrogen atom (Z = 1) or a hydrogen-like ion (Z > 1). In this model it is an essential feature that the photon energy (or frequency) of the electromagnetic radiation emitted (shown) when an electron jumps from one orbital to another, be proportional to the mathematical square of atomic charge (Z2). Experimental measurement by Henry Moseley of this radiation for many elements (from Z = 13 to 92) showed the results as predicted by Bohr. Both the concept of atomic number and the Bohr model were thereby given scientific credence. The atomic number is the number of _z_ an atom.

How does water move on its own concentration gradient?
kifflom [539]
Are you speaking of a density gradient, in which a more concentrated solution moves below a less concentrated solution?

In that case, the more concentrated solution has the greater density, and it will gradually sink below the less concentrated solution. 

In the same way, a stone will sink in water, which is less dense than the stone.
