GCSE/IGCSE Chemistry: Forming Ions PPT

This PowerPoint presentation goes through the basics of ion formation and is suitable for GCSE and IGCSE Level students. Metals are clearly shown to lose electrons, whereas non-metals are clearly shown to gain electrons. Key words such as ‘anion’ and ‘cation’ are included, and electron shell/‘dot and cross’ diagrams with sqaure brackets are given (i.e. in the same format as required by the exam).

Activities included (feel free to edit or modify after download):

• Whiteboard.fi starter
• Main teaching content (beginning from first principles with simple atomic structure, leading into ion formation)
• Google Doc suggested plenary (feel free to copy the slide into a Google Doc. or print for students to fill in)

Some syllabus references that this PPT satisfies (to name but a few):

AQA GCSE Chemistry:

4.2.1.1 Chemical Trends:* Ionic bonding occurs in compounds formed from metals combined with non-metals.*
4.2.1.2 Ionic Bonding: Students should be able to draw dot and cross diagrams for ionic compounds formed by metals in Groups 1 and 2 with non-metals in Groups 6 and 7.

**Edexcel IGCSE Chemistry: **

1.37: Understand how ions are formed by electron loss or gain
1.40: Draw dot-and-cross diagrams to show the formation of ionic compounds by electron transfer, limited to combinations of elements from Groups 1, 2, 3 and 5, 6, 7
