The effective atomic number for electron interactions may be calculated with a similar approach. [ 5 ] [ 6 ] The cross-section based approach for determining Z eff is obviously much more complicated than the simple power-law approach described above, and this is why freely-available software has been developed for such calculations.
In quantum chemistry, Slater's rules provide numerical values for the effective nuclear charge in a many-electron atom. Each electron is said to experience less than the actual nuclear charge , because of shielding or screening by the other electrons.
The effective atomic number Z eff, (sometimes referred to as the effective nuclear charge) of an electron in a multi-electron atom is the number of protons that this electron effectively 'sees' due to screening by inner-shell electrons. It is a measure of the electrostatic interaction between the negatively charged electrons and positively ...
Effective atomic number, denoted by Z eff, may refer to: Effective nuclear charge of an individual atom, as felt by electrons within that atom;
Where Z is the number of protons in the nucleus and is the average number of electrons between the nucleus and the electron in question. σ {\displaystyle \sigma \,} can be found by using quantum chemistry and the Schrödinger equation , or by using Slater's empirical formulas .
The atomic number increases within the same period while moving from left to right, which in turn increases the effective nuclear charge. The increase in attractive forces reduces the atomic radius of elements. When we move down the group, the atomic radius increases due to the addition of a new shell. [5] [6] [7]
The atomic number or nuclear charge number (symbol Z) of a chemical element is the charge number of its atomic nucleus. For ordinary nuclei composed of protons and neutrons , this is equal to the proton number ( n p ) or the number of protons found in the nucleus of every atom of that element.
