a)
Interpretation:
The largest atomic radius has to be identified from the give elements.
Concept Introduction:
Electronic configuration: The electronic configuration is the distribution of electrons of a given molecule or respective atoms in atomic or molecular orbitals.
The important there rules for electronic configuration given below:
Aufbau principle: This rule statues that ground state of an atom or ions electrons fill atomic orbitals of the lowest available energy levels before occupying higher levels. If consider the 1s shell is filled the 2s subshell is occupied.
Hund's Rule: The every orbital in a subshell is singly occupied with one electron before any one orbital is doubly occupied, and all electrons in singly occupied orbitals have the same spin.
Pauli exclusion rule: an atomic orbital may describe at most two electrons, each with opposite spin direction.
Atomic radius: The concept explain chemical element is a measured of the size of its atoms, in other words to measure the distance from the center of the nucleus to the boundary of the surrounding cloud of number of electrons.
Increase and decrease electro negativity: The less vacancy electrons an atoms has the least it will gain of electrons. Moreover the
Electron attachment enthalpy:
b)
Interpretation:
The most negative electron attachment enthalpy has to be predicted.

Increase and decrease electro negativity: The less vacancy electrons an atoms has the least it will gain of electrons. Moreover the electron affinity decrease down the groups and from right to left across the periods on the periodic table, the reason is electrons are placed in a higher energy level far from the nucleus thus a decrease from its pull.
Electron attachment enthalpy:
c)
Interpretation:
The element has to be ranked in increasing order of ionization energy.
