In hydrogen atom, the electron is making $$6.6\times 10^{15}rev/s$$ around the nucleus in an orbit of radius $$0.528A^0$$. The equivalent magnetic dipole moment is :

The velocity of the electron in 3rd orbit of hydrogen atom in $$cms^{-1}$$

In a hydrogen like sample electron is in 2nd excited state,the energy of the 4th state of this sample is -13.6 eV,then the incorrect statement is:

A $$p -$$orbital can accommodate upto:

The electron present in penultimate orbit of coinage metal atom are:-

The maximum number of electrons that can be contained in 

A trend common to both group $$I$$ and $$VII$$ elements in the periodic table as atomic number increase is 

The $$71^{st}$$ electron of an element $$X$$ with an atomic number of $$71$$ enters into the orbital:

Electronic transition in $${\text{H}}{{\text{e}}^{\text{ + }}}$$ would emit light in which region when $${{\text{e}}^{\text{ - }}}$$ jumps from fourth orbit to second orbit :

The electron in hydrogen atom is in the first Bohr's orbit (n=1). The ratio of electronic transition energies, $$ \Delta E(n=1\rightarrow n=3)\  to \ \Delta E(n=1\rightarrow n=2)\  is $$:
