Ionic Compounds

Question 1

What properties does ionic compounds have?

Answer 1

They have giant ionic lattice structures . They are regular . Electrostatic forces of attraction between oppositely charged ions in all direction

Question 2

What is the dissolvability boiling and conduction in ionic compounds?

Answer 2

High melting and boiling points due to strong attractions
Don’t conduct electricity because the ions are fixed in place and can’t move . Dissolve easily as ions separate free to move so they’ll carry an electric current

Question 3

What are positives of the atomic models?

Answer 3

2D allows the atoms are connected . What it contains
Dot and cross good showing how the molecules are formed
3D arrangement of ions
Ball and stick more realistic , easily visualise,

Question 4

What the negatives of the atomic models ?

Answer 4

2D doesn’t show the shape and the size
Dot and cross don’t show the size and how they’re arranged
3D onto show the outer layer
Ball and stick doesn’t show correct scales
