Ionic Bonding

Question 1

explain ionic bonding

Answer 1

electrostatic attraction after metal atom loses electrons to become a cation and non metal receive such electrons to become anions because they are unstable

Question 2

what are the 5 properties

Answer 2

high melt point
hard
brittle
conductivity in aqueous/liquid phase
solubility

Question 3

explain why ionic bonds have high melt point

Answer 3

the strong bonds require lots of thermal energy to break free

Question 4

explain why ionic bonds are hard

Answer 4

strong bonds make it hard to disrupt/separate lattice

Question 5

explain why ionic bonds are brittle

Answer 5

when force distorts the lattice the right positions are lost and electrons could be next to electrons which causes repulsion - shattering the lattice

Question 6

explain the conductivity of ionic bonds

Answer 6

olid ionic bonds cannot conduct bc no delocalised and tighlty packed
when solid melts (aqueous state) ions become free and can transmit charge
when solid dissolves in water (liquid state) the bonds are broken and the separate ions can conduct

Question 7

explain the solubility of ionic bonds

Answer 7

if soluble the ion break away and mix with the water molecules (depends on attraction)

Question 8

what is an example of an ionic compound

Answer 8

NaCl
