Concept introduction:
The ionization energy in periodic table
In periodic table the ionization energy is increases from left to right in a period due to increasing effective nuclear charge and it decreases from top to bottom of a group due to size of the atom is increases and the force of the attraction between centre of the nucleus and outer most electrons is decreases.
(b)
Interpretation:
The electron affinity of given hypothetical elements X and Z have to be comparatively explained.
Concept introduction:
Electron affinity is well-known as the electron gain enthalpy. Electron gain enthalpy is the amount of energy released when an isolated gaseous atom accepts an electron to form a monovalent gaseous anion.

If substitution would not occur at a significant rate under these conditions, check the box underneath the drawing area instead. Be sure you use wedge and dash bonds where necessary, for example to distinguish between major products. Note for advanced students: you can assume that the reaction mixture is heated mildly, somewhat above room temperature, but strong heat or reflux is not used.
