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

Velocity

$$ v_{\class{red}{n}} $$ Unit $$ \frac{\mathrm m}{\mathrm s} $$

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

Principal quantum number

$$ \class{red}{n} $$ 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

$$ \hbar $$ Unit $$ \mathrm{Js} $$

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

$$ m_{\text e} $$ Unit $$ \mathrm{kg} $$

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