Ionic Bonding
Cards in this deck (8)
- 1Define ionic bondingThe electrostatic attraction between positive and negative ions
- 2How are ions formed?Ions are formed as a result of electron transfer (NOT SHARING)
- 3In which compounds can ionic bonding be found?Compounds of a metal and a non-metal
- 4Complete the sentences: Ionic crystals are _______ ________ of ions. A giant ionic lattice forms because each ion is __________________ attracted in all directions to ions of the ___________ charge.Ionic crystals are GIANT LATTICES of ions. A giant ionic lattice forms because each ion is ELECTROSTATICALLY attracted in all directions to ions of the OPPOSITE charge.
- 5What are the properties of ionic compounds?Conducts electricity when molten or dissolved
High melting and boiling points
Soluble in water - 6Ions cannot conduct electricity when solid. Why?Ions in a liquid are free to to move (and carry a charge)
In a solid, they're fixed in position by strong ionic bonds - 7Explain why ionic compounds have high melting and boiling pointsGiant ionic lattices are held together by strong electrostatic forces
- 8Explain why ionic compounds are soluble in waterParts of the molecule have small negative and small positive charges (the molecules are polar). This means that the compounds can form hydrogen bonds with water.
