Important Formulas of Hydrogen Chapter

1. Rydberg Equation:

$\frac{1}{\lambda} = R_H \left(\frac{1}{n_1^2} - \frac{1}{n_2^2}\right)$

Where $R_{H}$ is the Rydberg constant $(1.097 \times 10^{7} m^{-1}), \lambda$ is the wavelength of the light, and $n_{1}$ and $n_{2}$ are positive integers.


2. Bohr's Radius: 

$r_n = \frac{0.529 \times 10^{-10}}{n}$

Where $r_{n}$ is the radius of the nth orbit, and n is the principal quantum number.


3. Energy of an Electron in nth Orbit:

$E_n = -\frac{2.18 \times 10^{-18}}{n^2}$

Where $E_{n}$ is the energy of the electron in the nth orbit.


4. De Broglie Wavelength:

$\lambda = \frac{h}{mv}$

Where $\lambda$ is the de Broglie wavelength, h is Planck's constant, m is the mass of the particle, and v is its velocity.


5. Heisenberg's Uncertainty Principle:

$\Delta x \cdot \Delta p \geq \frac{h}{4\pi}$

Where $\Delta x$ is the uncertainty in position, $\Delta p$ is the uncertainty in momentum, and h is Plack's constant.


6. Schrodinger Equation (Time-independent):

$\hat{H} \Psi = E \Psi$

Where $\hat{H}$ is the Hamiltonian operator, $\Psi$ is the wave function, and E is the total energy of the system.
