Ionic Bonding
Bayani Gaba-gaba
Table salt dissolves in water and conducts electricity when molten, yet it has a melting point above 800 degrees Celsius. These properties seem contradictory until you understand the bonding inside: oppositely charged ions locked together by powerful electrostatic forces in a giant lattice.
In this lesson you will learn how ions form by electron transfer, memorise the charges on common ions, write formulae for ionic compounds, draw dot-and-cross diagrams, and explain why ionic substances have high melting points yet conduct electricity only when molten or dissolved.
Manufura
- Understand how ions are formed by electron loss or gain
- Know the charges of common ions
- Write formulae for compounds formed between listed ions
- Draw dot-and-cross diagrams to show the formation of ionic compounds by electron transfer
- Understand ionic bonding in terms of electrostatic attractions
- Understand why compounds with giant ionic lattices have high melting and boiling points
- Know that ionic compounds do not conduct electricity when solid, but do conduct electricity when molten and in aqueous solution
