Aluminium has the highest nuclear charge, so its 2p peak should have the largest binding energy, but shielding effects reverse this trend.
Justify your answer.
The lifetime of (excited state) is
. If the excited state is

What makes TMS a molecule of choice to act as a reference in the NMR spectrometry?
5G services in India are provided at a frequency of . Calculate the wavelength of the radiation.
What is meant by polarizability of a molecule?
A light source of wavelength illuminates a metal surface and electron are ejected with the maximum kinetic energy 2 eV. If the same surface is illuminated by a light source of wavelength
, then calculate the maximum kinetic energy of the ejected electron. (Work function of metal is 1 eV)
