Answer

$\text{O}^+_2(15):\sigma\text{ls}^2\ \stackrel{*\ \ \ \ \ }{\sigma\text{ls}^2}\sigma\text{ls}^2\ \stackrel{*\ \ \ \ \ }{\sigma\text{ls}^2}\ \sigma2\text{s}^2\ \sigma2\text{p}_\text{z}^2\ \pi\text{2p}_\text{x}\ \pi\text{2p}_\text{y}^2\ \stackrel{*\ \ \ \ \ \ \ \ \ }{\pi2\text{p}_\text{x}^1}$

$\text{B.O.}=\frac12(10-5)=\frac52$

It is paramagnetic.

It has 6 pb of electrons.

$\therefore$ it has octahedral geometry.

Threshold frequency, $v_0$ is the minimum frequency which a photon must possess to eject an electron from a metal. It is different for different metals. When a photon of frequency $1.0 \times 10^{15} \mathrm{~s}^{-1}$ was allowed to hit a metal surface, an electron having $1.988 \times 10^{-19}$ J of kinetic energy was emitted. Calculate the threshold frequency of this metal. Show that an electron will not be emitted if a photon with a wavelength equal to 600 nm hits the metal surface.
