1f - ionic bonding Flashcards
What are ions?
Ions are electrically charged particles formed when atoms lose or gain electrons.
They have the same electronic structures as noble gases.
Sulfate ? Carbonate ? Nitrate ? Hydroxide ? Ammonium ? Silver ion ? Zinc ion ? Hydrogen ion ? Copper (II) ? Iron (II) ion ? Iron (III) ion ? Lead (II) ion ?
Sulfate = SO4 2- Carbonate = CO3 2- Nitrate = NO 3- Hydroxide = OH- Ammonium = NH 4+ Silver ion = Ag+ Zinc ion = Zn2+ Hydrogen ion = H+ Copper (II) ion = Cu 2+ Iron (II) ion = Fe2+ Iron (III) ion = Fe3+ Lead (II) ion = Pb2+
What is a Giant Ionic Lattice?
Giant three dimensional lattice structure held together by the strong attraction between oppositely charged ions.
What is ionic bonding in terms of electrostatic attractions?
Ionic bonding: a strong electrostatic attraction between oppositely charged ions.
Why do compounds with giant ionic lattices have high melting and boiling points?
Ionic compounds with Giant ionic lattices have high melting and boiling points because they have a giant structure with strong electrostatic forces between oppositely charged ions that require a lot of energy to break.
What is a giant structure?
Structure in which there are no individual molecules and the bonding extends in all directions.
What is an ion?
Charged particle formed when an atom (or group of atoms) loses or gains electrons.
What does molten mean?
Liquid state when solid has melted.
What is an ionic compound?
Formed when atoms of Metals transfer Electrons to atoms of Non-Metals to form Compounds made up of ions
Can ionic compounds conduct electricty? why?
Ionic Compounds cannot conduct electricity when in solid state as ions are fixed in structure and are not free to move. However, Ionic Compounds can conduct electricity when Molten or in Aqueous Solution as their ions are free to move to conduct an electric charge
