Summary of the specification content Learning outcomes What most candidates should be able to do Suggested timing (hours) Opportunities to develop Scientific Communication skills Opportunities to apply practical and enquiry skills Self/peer assessment Opportunities and resources Reference to past questions that indicate success 4.6.2.2 When a metal atom reacts with a non-metal atom electrons in the outer shell of the metal atom are transferred. Metal atoms lose electrons to become positively charged ions. Non-metal atoms gain electrons to become negatively charged ions. The ions produced by metals in groups 1 and 2 and by non-metals in groups 6 and 7 have the electronic structure of a noble gas (Group 0). The electron transfer during the formation of an ionic compound can be represented by a dot and cross diagram, eg for sodium chloride: The charge on the ions produced by metals in groups 1 and 2 and by non-metals in groups 6 and 7 relates to the group number of the element in the periodic table. Draw dot and diagrams for ionic compounds formed by metals in groups 1 and 2 with non-metals in groups 6 and 7 Work out the charge on the ions of metals and non-metals from the group number of the element, limited to the metals in groups 1 and 2, and in groups 6 and 7. Deduce that a compound is ionic from a diagram of its structure in one of the specified forms. Describe the limitations of using 1 Discussion questions: Name an electrically charged particle. What characteristic do poles of a magnet and positive/negative charges share? What is the role of this characteristic in chemical bonding? What does 'stability' mean and how can it be applied here? Tabulate common and state the charges of the ions formed. Extended writing: describe the bonding in the sodium chloride lattice using the correct terms, eg electrostatic forces of attraction. WS 1.2 Draw dot and cross diagrams for ionic compounds formed by What SI unit is charge measured in? Use magnesium ribbon to produce magnesium oxide. Discussion question: Why do we use dots and crosses? Draw the dot and cross diagram for this reaction. Model the sodium chloride lattice using molecular model kits. Students use periodic table to give quick-fire response to questions about charge on ions. Video clips: YouTube: YouTube: Teachit Science resource (23315) ‘Ionic bonding’ RSC (HT) RSC (HT)
