CSEC PHYSICAL SCIENCE LESSON 15 - Ionic Bonds

CSEC PHYSICAL SCIENCELESSON 15 - Ionic Bonds Describe the electron configuration of an atom that is most stable.VOCABULARY / CONCEPTS- valence electrons- stable electron configuration Valence electronsIn chemistry, valence electrons are the electrons of an atom thatcan participate in the formation of chemical bonds with other atoms. Stable electron configuration electron dot diagram Construct an electron dot diagram of the group A elements on the periodic table andpredict an elements properties.VOCABULARY / CONCEPTS- electron dot diagram Valence electrons Describe how an ionic bond forms and how ionization energy affects the process.VOCABULARY / CONCEPTS- ionic bond

Ionicbonds are formed between a cation, which is usually a metal, and an anion, which is usually a nonmetal. Pure ionic bondingcannot exist: all ionic compounds have some degree of covalent bonding. Examples of ionic bondslithium fluoride lithium chloride lithium bromide sodium fluoride sodium chloride sodium bromide potassium fluoride " Valence electrons Predict the composition of an ionic compound from its chemical formula.VOCABULARY / CONCEPTS- electron dot diagram Stable electron configuration Relate the properties of ionic compounds to the structure of crystal lattices.VOCABULARY / CONCEPTS- electron dot diagram Stable electron configuration
