# Question #cb6b8

##### 1 Answer

#### Answer:

Via Quantum Mechanics with lots and lots of math.

#### Explanation:

In Quantum Mechanics, there is the **Schrodinger Equation** . The equation is capable determining many properties of a particle in a system based on time and position of the particle.

In a steady state Schrodinger Equation (we are not interested in the time variable);

The equation is

**wave function** of a particle; a function that describes the nature of your particle.

Lets see the hydrogen atom, the easiest one.

**orbital shell** (also energy state).

What we want to do is to **solve** the Schrodinger equation to **find #psi#.**

Solving the equation is very tedious and requires arbitrary constants **Separation of Variables method ** .

Solving this implies that ** #psi# has non-zero value if the values of #l# has integer values and does not exceed #n-1#** .

In other words, if

The electron will cease to exist.

Therefore, if

Sorry if I can't express this any simpler. The history of the atomic model from Neils Bohr onwards is very theoretical.
