Slide 1: Introduction to Ionic Bonding

Main Teaching Points:

• Definition: Ionic bonding as electrostatic attraction between oppositely charged ions.
• Formation of ions: Metals lose electrons (cations), non-metals gain electrons (anions).
• Ionic compounds: Formation from metal + non-metal.
• Relevance to real-world chemistry (e.g., salts, electrolytes).

Success Criteria:

• Students can define ionic bonding using AQA terminology.
• Students can explain how ions form and attract.
• Students can identify compounds likely formed by ionic bonding.

Differentiation:

• Use simplified vocabulary and sentence structures for SEND learners.
• Visual aids: Ionic formation animation or simple diagrams of electron transfer.
• Use a glossary slide or handout of key terms.

Extension:

• Challenge students to predict ionic charge for metals and non-metals outside the first 20 elements.
• Discuss the role of ionic bonding in biological systems (e.g., nerve impulses).

Dyslexia-Friendly Tips:

• Use large, sans-serif fonts (Arial or Comic Sans).
• Colour-code ions: cations blue, anions red.
• Keep text minimal per bullet, with plenty of spacing.

Slide 2: Electron Transfer and Ion Formation

Main Teaching Points:

• Detailed stepwise electron loss and gain.
• Illustration of Na → Na⁺ + e⁻ and Cl + e⁻ → Cl⁻.
• Use of Lewis dot structures to show electron transfer.

Success Criteria:

• Students can draw Lewis structures for ionic bonding examples.
• Can describe electron transfer process in terms of energy changes.

Differentiation:

• Provide partially completed Lewis diagrams for SEND students to complete.
• Use coloured counters or magnetic models in class for tactile learners.

Extension:

• Examine transition metals’ variable ionic states briefly, linking to advanced chemistry.
• Explore concepts of first ionisation energy and electron affinity as underpinning forces.

Dyslexia-Friendly Tips:

• Use consistent colour coding and symbols for electrons/lone pairs.
• Present one step per line and use bullet numbers.
• Avoid long paragraphs.

Slide 3: Properties of Ionic Compounds

Main Teaching Points:

• High melting and boiling points due to strong electrostatic forces.
• Electrical conductivity in molten/dissolved state, not solid.
• Solubility trends in water.
• Giant ionic lattice structure diagram.

Success Criteria:

• Students can describe ionic compound properties with explanations linked to bonding.
• Students can sketch a simple ionic lattice.

Differentiation:

• Use labelled diagrams with annotations for SEND learners.
• Provide sentence starters (“Ionic compounds have high melting points because...”) to scaffold explanations.
• Use real samples or videos showing ionic crystals dissolving/conducting electricity.

Extension:

• Discuss lattice enthalpy and its influence on melting points.
• Investigate exceptions and link to polarisation effects or covalent character.

Dyslexia-Friendly Tips:

• Use clear, simple fonts and bullet points.
• Illustrate concepts with visuals before introducing text.
• Use ample white space on slides.

Slide 4: Ionic Bonding and the Periodic Table

Main Teaching Points:

• Linking group 1 & 2 metals and group 6 & 7 non-metals to ionic formation patterns.
• Predicting formulas of ionic compounds using charges and cross-over method.
• Use examples: NaCl, MgO, Al₂O₃.

Success Criteria:

• Students can predict ionic formulae from element symbols and charges.
• Students explain pattern of ionic bonding across groups/families.

Differentiation:

• Provide charge charts and worked examples for SEND pupils.
• Let students use physical model kits to build formulae.
• For low ability, simplify examples; for higher ability, use polyatomic ions or transition metal ions.

Extension:

• Explore ionic bonding vs covalent bonding trends across the periodic table in detail.
• Connect to GCSE recap and how it deepens understanding for A level.

Dyslexia-Friendly Tips:

• Use tables with alternating row colours for clarity.
• Use symbols with clear spacing and avoid overcrowding info.
• Read-through activity with paired discussion.

• Students identify elements of ionic lattice in diagrams.
• Clear links made between structure, bonding and properties.

Differentiation:

• Use multiple choice or matching questions for SEND learners.
• Allow use of notes or periodic table.
• Provide sentence starters for written answers.

Extension:

• Pose a challenging question, e.g.: “Explain why Mg²⁺ ions have a different effect on lattice enthalpy compared to Na⁺ ions”.

Dyslexia-Friendly Tips:

• Use clear spacing.
• Short, direct questions in bullet form.
• Provide answer templates for writing.

Slide 6: Summary and Reflection

Main Teaching Points:

• Recap of ionic bonding definitions, ion formation, properties & periodic trends.
• Importance of ionic compounds in industry/biology.
• Highlight success criteria met.

Success Criteria:

• Students verbalise or write one thing they’ve learned.
• Students note one question/area for further study.

Differentiation:

• Use think-pair-share activity for pupil engagement.
• Allow drawing or mindmapping for SEND learners instead of writing.

Extension:

• Ask students to create a short explanation video or infographic for peers.

Dyslexia-Friendly Tips:

• Use bullet points and visuals for summary.
• Keep reflective questions simple and open-ended.
