P: Kernel is the nucleus and all other electrons in the atom except the outer most shell electrons. Q Valency is the outermost shell.

Assertion (A): Atomic radii of elements decrease across a period from left to right. Reason ( R_1 ): Nuclear charge increases. Reason ( R_2 ): No. of shells increases.

Assertion (A) While going from left to right of the periodic table, the atomic size decreases more rapidly for the 3d-series compared to the 4 f-series of elements. Reason R 3d-electrons experience lesser shielding then 4 f-electrons. The correct answer is

The following are some statements about periodic properties i) Atomic size decreases from left to right in a period ii) The EA of 2nd element in VA, VIA, VIIA are greater than the first element iii) Acidic nature of oxides decreases and basic nature of oxides of elements increases down the group

Screening effect is the effect produced by intervening electron 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. Balance electrons are attracted by nucleus and repelled by other electrons. Net attractive force on electron under consideration =Z- sigma = (Nuclear charge screening effect) which is Slater's formula for screening constant. If one electron is present in outermost orbit, there will be no screening in that orbital. Each electron contributes 0.35 (total electrons minus 1) present in outermost shell. In penultimate energy level, electrons contribute 0.85. A contribution of 1.0 is from remaining electrons (present in last but one energy level). The effective nuclear charge for 4s electrons of Zn will be

It is not possible to measure the atomic radius precisely since the electron cloud surrounding the atom doesnot have sharp boundary. One practical approach to estimate the size of an atom of a non-metallic element is to measure the distance between two atoms when they are bound together by a single bond in a covalent molecule and then dividing by two. For metals we define the term "metallic radius" which is taken as half the internuclear distance separating the metal cores in the metallic crystal. The vander Waal's radius represents the overall size of the atoms which includes its valence shell in a nonbonded situation. It is the half of the distance between two similar atoms in separate molecules in a solid. The atomic radius decreases across a period and increases down the group. Same trends are observed in case of ionic radius. Ionic radius of the species having same number of electrons depends on the number of protons in their nuclei. Atomic radii of the noble gases are larger than the precedent elements of the same periods because

Passage-IV : Sulphur and rest of the elements of group 16 are less electronegative than oxygen. Therefore, their atoms cannot take up electrons easily. They can acquire ns^(2)np^(6) configuration by sharing two electrons with the atoms of other elements and thus, exhibit +2 oxidation state in their compounds. In addition to this, their atoms have vacant d-orbitals in their valence shell to which electrons can be promoted from the p and s-orbitals of the shell. As a result, they can show +4 and +6 oxidation states shell. The nature of the compounds of sulphur having +4 oxidation state is :
