all have the same no. of electrons in their outer shell

Question 9

what is an ionic compound?

Answer 9

a compound that only contains ionic bonds

Question 10

what is a giant ionic lattice?

Answer 10

when ions are closely packed with electrostatic forces of attraction between oppositely charged ions in all directions

Question 11

what are the features of ionic compounds?

Answer 11

high melting and boiling points due to the strong bonds

Question 12

are ionic compounds able to conduct electricty?

Answer 12

yes, when in molten form and also when they are dissolved in water as the ions are free to move
