Forming Ions and Ionic Bonding | BTEC Applied Science Unit 1

A complete, ready-to-teach lesson for Unit 1 (Principles and Applications of Science I), chemistry section: electron transfer, ion configurations and dot-and-cross diagrams for ionic compounds.

Learning objectives:

• Predict the charge on an ion from the position of the element in the periodic table.
• Write electron configurations of ions and identify isoelectronic noble gases.
• Draw dot-and-cross diagrams to show the formation of ionic compounds.
• Deduce formulae of ionic compounds and describe the ionic lattice.

What’s included:

• Student worksheet (PDF and editable Word)
• Teacher version with model answers and mark schemes (PDF and editable Word)
• Teacher notes: lesson flow, common misconceptions and practical/safety notes
• Retrieval starter (5 marks)
• Structured tasks with key-idea boxes and clear diagrams
• Check for Understanding quiz (10 marks) with a confidence self-assessment
• Exam-style practice (15 marks), ending with a levels-marked 6-mark question with indicative content

Specification coverage:

• A1 · Ionic bonding: ions formed by electron transfer; the electrostatic attraction between oppositely charged ions.
• A1 · Electronic structure: electron configurations and dot-and-cross diagrams of ions.

About 60 minutes of teaching; the exam-style section works in class or as homework. All questions are original.
