5.2 what are properties of ionic substances

Question 1

structural properties of ionic compounds

Answer 1

ionic compounds have giant ionic crystal lattice structures

Question 2

describe the giant ionic crystal lattice structure

Answer 2

the lattice consists or large numbers of alternating positive and negative ions held together by electrostatic forces of attraction

Question 3

melting and boiling points of ionic compounds

Answer 3

have high melting and boiling points

Question 4

why do ionic compounds have high melting and boiling points

Answer 4

because the mutual electrostatic attraction between oppositely charged ions are strong, a large amount of energy is needed to overcome these forces

Question 5

what state are ionic compounds at room temperature

Answer 5

solid

Question 6

hardness of ionic compounds

Answer 6

ionic compounds are resistant to deforming and tend to be hard

Question 7

why are ionic compounds hard

Answer 7

the mutual electrostatic attraction between oppositely charged ions also make them resistant to deforming and tend to be hard as their attractive forces cause the ions to resist motion

Question 8

ionic compounds are hard but __

Answer 8

brittle
