Structure of At...

When an electron from an excited hydrogen atom undergoes transition from energy level  n = 4  to  n = 2, the emission of radiations will give rise to 

Bohr’s model of atom could explain quantitatively the general features of the structure of  

The product of the uncertainties of the exact position and exact momentum (or velocity) of an electron. The product of their uncertainties is always

The orbital with quantum numbers n = 4, l = 3 is 

Arrange the electrons present in the 4s, 3d, 4p and 3p orbitals in the order of their increasing energies

Give the name and atomic number of the inert gas atom in which the total number of d-electrons is equal to the difference between the numbers of total p and total s electrons.

If a cation B³⁺ has 18 electrons, the atomic number of element B will be

Among the following pairs of orbitals 2s and 3s, 4d and 4f, 3d and 3p, the orbitals that will experience the larger effective nuclear charge will be
