The total energy of an electron in the first excited state of $H$-atom is $-3.4 \mathrm{eV}$, then its potential energy is in this state is _____ $\mathrm{eV}$.

The ionization potential of hydrogenic ions $P$ and $Q$ are $V_{\mathrm{P}}$ and $V_{\mathrm{Q}}$ respectively. If $V_{\mathrm{Q}}<V_{\mathrm{P}}$ then radii

In the discharge tube as the density of atom increases, the intensity of spectral lines

Wavelength of characteristic X-ray depends on which property of target? $\left(\text{where}, A=\text{Mass number}, Z=\text{Atomic number}\right)$
