Assertion (A) : Anything that influences of the valence electorns will affect the chemistry of the element. So, the nuclear molar mass does not affect the valence shell. Reason (R ) : Nucleus contains protons and neutrons, whereas protons i.e. nuclear charge affects the valence shell but neutrons doe not.

Consider the following statements and arrange in the order of true/false as given in the codes. S_1 :In modern periodic table each block contains a number of columns equal to the number of electrons that can occupy that sub-shell S_2 :The greatest increase in ionization enthalpy is experienced on removal of electron from core noble gas configuration S_3 :The size of the isoelectronic species is effected by eletron-electron interaction in the outer orbitals S_4 :Any thing that influences the valence electrons will affect the chemistry of the element and the valence shell is not affected by nuclear mass.
