The discussion revolves around the question of why the first ionisation energy of chlorine is higher than that of sulfur. Participants explore concepts related to atomic electron binding energy, including nuclear charge and shielding effects, within the context of a homework-related inquiry.
Participants generally agree on the importance of showing effort and understanding in tackling the question. However, there is no consensus on the specific reasoning behind the differences in ionisation energies of chlorine and sulfur, as the original poster has not provided their approach.
The discussion highlights the need for clarity on concepts such as nuclear charge and shielding effects, but does not resolve how these factors specifically relate to the ionisation energies in question.

compare nuclear charge and shielding effect. guess i can't tell you too much since you didnt even try the qn 
As semc indicated, the point of learning is to understand the subject, not simply to answer test questions! semc also points you in the right direction. What determines the binding energy of an atomic electron?rpatel said:
