Quick comprehension check
“Consider nitrogen (N) and fluorine (F). Which element has the higher electronegativity? Explain your answer in terms of effective nuclear charge and electron configuration. Consider lithium (Li) and potassium (K). Which element has the larger atomic radius? Explain your answer in terms of electron configuration and the number of electron shells.”
