calculate effective nuclear charge of gallium
Answers
Answer:
The effective nuclear charge is the net positive charge experienced by an electron in a polyelectronic atom. The term "effective" is used because the shielding effect of negatively charged electrons prevent higher orbital electrons from experiencing the full nuclear charge of the nucleus due to the repelling effect of inner-layer electrons. The effective nuclear charge experienced by the electron is also called the core charge. It is possible to determine the strength of the nuclear charge by the oxidation number of the atom. Most of the physical and chemical properties of the elements can be explained on the basis of electronic configuration. Consider the behavior of ionization energies in the periodic table.
Answer:
The effective nuclear charge is the net positive charge experienced by valence electrons. It can be approximated by the equation: Zneff = Z – S, where Z is the atomic number and S is the number of shielding electrons.
