filling the orbitols by electrons using hund s rule

Electron pairing will not take place in orbitals of same energy (same sub-shell) until each orbital is first singly filled with parallel spi..

According to this rule, electron pairing will not take place in orbitals of same energy (same sub-shell) until each orbital is first singly filled with parallel spin. In other words in a set of orbitals having same energy (degenerate orbitals), the electrons..

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 Aufbau principle as already discussed f..

fig 1.6 - Energy level diagram for a multi-electron atom The energy level diagram for a multi-electron atom is as shown above. The filling of orbitals is governed by the following rules: 1) Aufbau principle 2) Pauli's exclusion principle 3) Hund's h..

The Born Haber cycle can be used for the calculation of electron affinities of some elements that are otherwise very difficult to measure. Heat of formation of a compound may be expressed as: S, D H f , D, and IE are experimentally determined and lattice energy, U ..

The relative abundance of noble gases along with their electronic configurations is given in the table. Electronic configurations of noble gases Element Symbol Atomic No. Electronic Configuration Abundance In Earth’s Crust (in ppm) ..

The direction of induced current can easily be predicted using Fleming's right hand rule. If we stretch the first finger, the central finger and the thumb of our right hand in mutually perpendicular directions such that first finger points along the direction of the field and th..

All the digits from 1, 2, 3, 4, ., 9 are significant digits. Zeros (0s) if they occur between non-zero digits, are significant For example, in the number- 325007, 2409, 308, zeros in between the digits are significant. The final zeros (0s) of an approximated number when e..

We are familiar with the fact that the atoms of all elements, except noble gases, have an incomplete outermost shell. Consequently, most elements are reactive and they try to achieve the stability of the noble or inert gases by electron transfer or by electron sharing. After th..
