The effective nuclear charge of N atom is :

This question has statement I and Statement II. Of the four choices given after the Statements, choose the one that best describes the two Statements. Statement-I: The acidic nature of some cations is Al^(3+)gtBe^(2+)gtNa^+gtK^+ Statement-II: More is the effective nuclear charge on cation more is its acidic nature.

What is the effective nuclear charge at the periphery of nitrogen atom when a extra electron is added during the formation of an anion. Compare the value of Z_eff when the atom is ionized to N^+ .

The unpaired electrons in Al and Si are present in 3p orbital. Which electrons will experience more effective nuclear charge from the nucleus?

Among the following pairs of orbitals which orbital will experience the larger effective nuclear charge? (1) 2s and 3s. (2) 4d and 4f, (3) 3d and 3p.

What is the relationship between effective nuclear charge and screening constant?

What is the effective electric charge of a hole?

Calculate the effective nuclear charge experienced by the 4s electron in potassium atom.

Screening effect is the effect produced by intervening electrons between nucleus and valence electrons . They shield the nucleus from valence electron and effective nuclear charge decreases if there is less shielding effect the effective nuclear charge decreases Valence electrons are attracted by nucleus and repelled by other electrons. Net effective force on electrons under consideration = Z-sigma = (Nuclear charge -screening effect ) slaters formula for screening constant. If one electron is present in outermost orbit there will be no screening in that orbital. Each electrons contributes 0.35 (total electrons minus 1) present in outermost shell. In penultimate energy level electrons contribute 0.85. A contribution of 1 is from remaining electrons (present in last but one energy level) The effective nuclear charge for 4s electrons of Zn will be
