What is quantum?

Photon is quantum of radiation with energy E = hv, where v is frequency and h is Planck's constant. The dimensions of h are the same as that of

Explain various quantum numbers.

Describe the orbital with quantum number n=5 and l=3

On the basis of quantum number justify that sixth period of periodic table should have 32 elements.

Show that the wavelength of electromagnetic radiation is equal to the de-Broglie wavelength of its quantum (Photon).

An important parameter of a photochemical reaction is the quantum efficiency or quantum yield (phi) which is defined as phi=("moles of the substance reaction")/("moles of photons absorbed") Absorption of UV radiation decompose acetone according to the reaction (CH_(3))_(2)COoverset(hv)(rarr)C_(2)H_(6)+CO The quantum yield of a reaction at lambda=330nm is 0.4 . A sample of acetone absorbs monochromatic radiation at lambda330mn at the rate of 7.2xx10^(-3)Js^(-1) (given : N_(A)=6xx10^(23), h=6.6xx10^(-34) in S.I unit). The rate of formation of CO(mol//s) is : a) 2xx10^(-8) b) 8xx10^(-8) c) 8xx10^(-9) d) none of these
