Ionic bonding

Question 1

what is it?

How it happens?

Answer 1

transfer of electrons between
metal/non metal atoms form cations/anions
metal loses electron +non metal gain electron -
oppositely charged ions strongly attracted to each other by electrostatic forces

Question 2

When drawing diagrams to show ionic compounds what do we use ?

Answer 2

dots and crosses with arrows

Question 3

Ionic compound properties
Structure
Forces of attraction?

Answer 3

lattice
regular arrangement of ions
held together by electrostatic forces(oppositely charged ions)
conduct electricity only when dissolved in water
high melting points

Question 4

Explain why ionic compounds have high melting points

and only conduct electricity when in dissolved in water or in liquid form

Answer 4

high melting points-have strong,inter molecular electrostatic forces a lot of energy required to overcome this.
solution-electrons free to move and carry their own charge = become a sea of delocalised electrons
in solid state ions balance each other out and are neutral
