The effective nuclear charge (Z) has to explained for given Lithium (Li) to fluorine (F) atoms. Concept Introduction: Nuclear charge (Z): The effective nuclear charge generally denoted by ( Z eff or Z* ) it is the net positive charge experienced by an electron in a multi-electron atom. This word “effective” is used because the shielding effect of negatively charged electron prevents higher orbital electrons experience the full nuclear charge. Increase and decrease electro negativity: The less vacancy electrons an atoms has the least it will gain of electrons. Moreover the electron affinity decrease down the groups and from right to left across the periods on the periodic table, the reason is electrons are placed in a higher energy level far from the nucleus thus a decrease from its pull.
