Avogadro's number is one of the most important constants used in chemistry. It is the number of particles in a single mole of a material, based on the number of atoms in exactly 12 grams of the isotope carbon12. Although this number is a constant, it's experimentally determined, so we use an approximate value of x 10 , you know how many atoms are in a mole.

Atomic clock Wikipedia

For both types the atoms in the gas are prepared in one electronic state prior to filling them into the cavity. For the second type the number of atoms which change electronic state is detected and the cavity is tuned for a maximum of detected state changes. Most of the complexity of the clock lies in this adjustment process.
