Students in a previous year were asked a certain set of questions. For each of the questions and the given responses, in the corresponding boxes, identify whether the student response is correct or incorrect and the corrections that need to be made.
a)
Question:
IE for O = 1310 kJ/mol and IE for Cl = 1250 kJ/mol. Explain why this difference exists.
Student’s response:
Because Cl has a higher n-value the electrons are further from the nucleus, giving the atom more room and the ability to add additional electron(s).

The
Z
eff
for Cl is:
