Radius

Unit
The quantized radius of the orbit of an electron in the \(\class{red}{n}\)-th state in the framework of the Bohr model.

Velocity

Unit
The quantized velocity of the electron in the \(\class{red}{n}\)-th state in the framework of the Bohr model.

Principal quantum number

Unit
The principal quantum number \( \class{red}{n} = 1, 2, 3, ...\) numbers the discrete energy states of an electron in the atom.

Reduced Planck's constant

Unit
Reduced Planck's constant is a physical constant (of quantum mechanics) and has the value: \( \hbar ~=~ \frac{h}{2\pi} ~=~ 1.054 \,\cdot\, 10^{-34} \, \text{Js} \).

Electron mass

Unit
The rest mass of an electron is a physical constant with the value: $$ m_{\text e} ~=~ 9.1 ~\cdot~ 10^{-32} \, \mathrm{kg} $$
