What you’ll learn4 learning objectivesChoose one objective for a focused lesson, or study the complete topic.3.1.1Electronegativity• Define electronegativity as the power of an atom to attract electrons to itselfSyllabus objective3.1.2Factors influencing the electronegativities• Explain the factors influencing the electronegativities of the elements in terms of nuclear charge, atomic radius and shielding by inner shells and sub-shellsSyllabus objective3.1.3The trends in electronegativity across• State/explain: the trends in electronegativity across a period and down a group of the Periodic TableSyllabus objective3.1.4The differences in Pauling electronegativity• Use the differences in Pauling electronegativity values to predict the formation of ionic and covalent bonds (the presence of covalent character in some ionic compounds will not be assessed) (Pauling electronegativity values will be given where necessary)Syllabus objective
