Bonding Flashcards
What is the definition of giant ionic lattice?
strong electrostatic attraction between a positive metal and a negative non-metal
why do giant ionic lattices have high MP and BP?
high MP and BP because of strong electrostatic attraction require a lot of energy to overcome
why do giant ionic lattices conduct when molten/melted/in solution?
free ions to carry the charge
why do giant ionic lattices not conduct in a solid?
no free ions to carry the charge
what is the definition of simple covalent bonding?
weak intermolecular bonds between a non-metal and another non-metal. They share 1 or more electrons to get a full outer shell
why does simple covalent bonding have low MP and BP?
weak intermolecular forces require little energy to overcome
why does simple covalent bonding not conduct?
no free electrons or ions
what is the definition of metallic bonding?
strong electrostatic attraction between a positive metal and a negative delocalised electron
why does metallic bonding have high MP and BP
the strong electrostatic attraction that requires a lot of energy to break
does metallic bonding conduct?
yes because delocalised electrons carry charge
