4 atomic orbitals

Atomic Orbitals - Electrons cannot exist at a particular point or in a well-defined orbit (path), according to the above new approach called wave mechanics. This led to the concept of 'most probable regions'. We talk about 'certain regions in space around the nucleus c..

For Hydrogen atom Z = 1 i.e., r a n 2 the stationary orbits are not equally spaced On substituting the value h = 6.6x10 - 3 4 J-sec n = 1 K = 9 x 10 9 Nm 2 /c 2 m = 9.1 x 10 - 3 1 kg e = 1.6 x 10 - 1 9 c, we get r = 5.29 x 10 - 1 1..

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 combinat..

Shapes of Atomic Orbitals - An atomic orbital is the space around the nucleus in which the probability of finding the electron is maximum. These most probable regions can be diagrammatically represented by cloud density (dot) diagrams. The density of dots (or..

Atomic orbital Molecular orbital An electron in atomic orbital isunder the influence of only one positive nucleus of the atom An electron in molecular orbital is under the influence of two or more nuclei depending ..

An atomic orbital is the space around the nucleus in which the probability of finding the electron is maximum. These most probable regions can be diagrammatically represented by cloud density (dot) diagrams. The density of dots (or lack of them) in any region of the cloud ..

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 illustrates the relative energy of..

For p-orbitals (l=1), there are three possible orientations corresponding to m = -1, 0, +1 values. This means that there are three p - orbitals in each p-subshell. These are designated as p x , p y and p z ; For e.g., 2p x , 2p y and 2p z . fig 1.4 - (a) Shapes of thre..
