orbitals in energy level 3

Single electron atoms - The relative energies of various orbitals of single electrons depend on the value of the principal quantum number 'n' and is independent of the value of 'l'. This can be shown by an arrangement known as energy level diagram. The diagra..

The relative energies of molecular orbitals depend upon the following two factors: (i) the energies of the atomic orbitals combining to form molecular orbitals. (ii) the extent of overlapping between the atomic orbitals..

The relative energies of various orbitals of single electrons depend on the value of the principal quantum number 'n' and is independent of the value of 'l'. This can be shown by an arrangement known as energy level diagram. The diagram given below illu..

. It should be noted that the probability of finding the electron in a particular p orbital is equal in both the lobes. The p orbitals of higher energy levels (n = 3, 4, 5 etc.) have similar shapes although their sizes are bigg..

>a 2s orbital differs from 1s orbital in being larger in size and having a nodal surface . The higher s orbitals have also spherical shapes and number of nodal surfaces in s orbital for any given energy level is n - 1, where n represents h..

Rules for Filling Molecular Orbitals - The following rules are followed for filling up molecular orbitals with electrons in order to write molecular configurations: 1. The molecular orbital having the lowest energy is filled first. This is in accordance with ..

For d-orbital (l = 2), there are five possible orientations corresponding to m = - 2, -1, 0, + 1, +2. This means that there are five orbitals in each d-subshell. For 3d subshell, these are designated as 3d x y , 3d y z , 3d x z , ..

Shapes of d orbitals - For d-orbital (l = 2), there are five possible orientations corresponding to m = - 2, -1, 0, + 1, +2. This means that there are five orbitals in each d-subshell. For 3d subshell, these are designated as 3d x y , 3d y..

Conditions for the Combination of Atomic Orbitals - Molecular orbitals are formed by the combination of atomic orbitals. But all types of orbitals cannot combine with each other. The following are the main conditions for effective combination of atomic o..

> How do infrared and g - rays differ in their (i) wavelength and (ii) penetrating power. Suggested Answer:- (i) g - rays have much shorter wavelengths of the order of 10 - 1 3 m while the infrared have longer wavelengths of the order of 10 - 6 or more. (ii) g - rays have a much higher pe..
