The order of screeing effect of electrons of s,p,d and f orbitals of a given shell of an atom on its outer shell electrons is:

Nuclear charge actually experienced by an electron is termed as effective nuclear charge. The effective nuclear charge Z^(**) actuall ydepends on type of shell and orbital in which electron is actually present. The relative extent to which the various orbitals penetrate the electron clouds of other orbitals is s gt p gt d gt f (for the same value of n) The phenomenon in which penultimate shell electrons act as screen or sheild in between nucleus and valence shell electrons and thereby reducing nuclear charge is known as shielding effect. the penultimate shell electrons repel the valence shell electron to keep them loosely held with nucleus. it is thus evident that more is the shielding effect, lesser is the effective nuclear charge and lesser is the ionization energy. Q. Which of the following valence electron experience maximum effective nuclear charge?

An atom has 2 electrons in K shell, 8 electrons in L shell and 6 electrons in M shell. The number of s-electrons present in that element is

Q. Ionzation enegy is not influenced by:

Assertion: Shielding effect increases as we go down the group. Reason: More is the number of electrons in the penultimate shell, more is shielding.

the percentage of orbitals occupied by electrons out to total orbitals present upto the outermost shell of Fe atom :
