Which reaction requires the most energy? 
A. N(g) → N+(g) + e - 
B. N+(g) → N2+(g) + e - 
C. F(g) → F+(g) + e - 
D. F+(g) → F2+(g) + e - - D. F+(g) → F2+(g) + e - 
Fluorine has a higher effective nuclear charge than Nitrogen - so it is harder to remove an electron 
(takes more energy because the electron is more strongly attracted by the nucleus). Effective nuclear 
charge is the same for F and F+ because the number of protons and core electrons are not changed. 
However, when the numb...

What is the role of the Pauli exclusion principle in determining the electron configuration of 
atoms? 
 
 The Pauli exclusion principle states that no two electrons in an atom can have the same set 
of quantum numbers, which helps determine the unique electron configuration and arrangement 
in orbitals. 
 
How do isotopes of the same element differ from each other? 
 Isotopes of the same element have the same number of proton...
