Now, 1 molecule of urea has total of 8 atoms, out of which 4 atoms are of H, 2 atoms are of N, 1 of C, and 1 of O. ∴ Number of H atoms in 5.6 g of urea = (4 × 0.0933) mol × 6.022 × 10 23 atoms/mol = 2.247 × 10 23 atoms of hydrogen. ∴ Number of N atoms in 5.6 g of urea = (2 × 0.0933) mol × 6.022 × 10 23 atoms/mol = 1.124 × 10 23

The rate of reaction for molecular hydrogen (Basically, how quickly the molecular hydrogen is formed) depends both on the concentration of atomic hydrogen and on the temperature. Z is the atomic number of the atom (so it's 2 for Helium, 3 for Lithium, or 6 for Carbon). That's right. They're exactly the same as for hydrogen, except with an extra Z^2 term.

We see that Bohr’s theory of the hydrogen atom answers the question as to why this previously known formula describes the hydrogen spectrum. It is because the energy levels are proportional to [latex]\frac{1}{n^2}\\[/latex], where n is a non-negative integer. A downward transition releases energy, and so n i must be greater than n f. The various series are those where the transitions end on a certain level.

In fact, a hydrogen atom should exist for no longer than 5 × 10 − 11 sec, time enough for the electron's death spiral into the nucleus. This is one of the worst quantitative predictions in the history of physics. It has been called the Hindenberg disaster on an atomic level.
