CAIE IGCSE Chemistry 2.4.6 Formation of Ionic Bonds Between Ions Questions

Represent ionic bond formation in CAIE IGCSE Chemistry Extended by tracking transferred electrons, showing charged ions and matching the number of ions to the diagram requested.

Exam points

Use electronic structures to select a metal and a non-metal that can form an ionic compound, with electrons transferred from the metal to the non-metal.
Draw the ions after electron transfer with complete outer shells, distinct dot-and-cross electron origins and the correct positive or negative charges.
Show the number of each ion requested: a complete compound-ion group may need several identical ions, while a prompt for one ion of each type needs only those specified ions.

[Maximum number: 1]

The electronic structures of two atoms, P and Q, are shown.
