Ionice Bonding Flashcards
(7 cards)
1
Q
What does ionic bonding consist of?
A
a metal and non metal
2
Q
what are the properties of ionic bonding
A
- high melting point
- brittle
- conduct in only liquid / aqueous form
- hard
3
Q
why does it have a high melting / boiling point?
A
Electrostatic forces of attraction are so strong, needs great amount of energy to overcome those forces.
4
Q
why is it hard?
A
due to large lattice, lots of atoms to exert equal and opposite force back at you.
5
Q
why are they brittle?
A
distortion to lattice causes electrostatic repulsion between charged ions (opposites attract)
6
Q
why do they only conduct in aqueous form?
A
because in liquid form, ions are delocalised and mobile which allows flow of charge.
7
Q
why can’t they conduct in solid form?
A
because ions are localised and ions are immobile in the lattice making charge not being able to flow
