Electronegativity

Module 1

IQ4: What binds atoms together in elements and compounds?

Students:

● investigate the role of electronegativity in determining the ionic or covalent nature of bonds between atoms

● investigate the differences between ionic and covalent compounds through:

• using nomenclature, valency and chemical formulae (including Lewis dot diagrams)

• examining the spectrum of bonds between atoms with varying degrees of polarity with respect to their constituent elements’ positions on the periodic table

• modelling the shapes of molecular substances
