Webb15 aug. 2024 · The octet rule doesn't actually say the highest shell should have eight electrons. It says that the atom achieves stability by gaining the electronic configuration of the nearest noble gas. Noble gases have the general configuration s 2 p 6 ( 8 electrons?), but as demonstrated above, these 8 electrons may not be in the highest shell. WebbIf Aufbau rule is not obeyed and the electronic filling occurs orbit by orbit till saturation is reached (for a given principal quantum number n, electrons are filled in the increasing order of azimuthal quantum number l ), then the percentage change in sum of all (n+l) values for unpaired electrons in an atom of iron is 10x.

The rule states that, for a stated electron configuration, the greatest value of spin multiplicity has the lowest energy term. It says if two or more than two orbitals having the same amount of energy are unoccupied then the electrons will start occupying them individually before they fill them in pairs. shannon cullinane norwoodWebbDescription. The combining capacity, or affinity of an atom of a given element is determined by the number of hydrogen atoms that it combines with.
