6.2 Ionic Compounds

Question 1

electrostatic attraction

Answer 1

The attraction between opposite charges.

Question 2

ionic bond

Answer 2

the electrostatic attraction between oppositely charged ions

Question 3

Lattice structures

Answer 3

The organized patterns of positive and negative ions. Determined by the relative sizes of the ions and their charges.

Question 4

Lattice Structure of NaCl

Answer 4

A 3D, alternating array of oppositely charged ions

Question 5

The transfer of electrons during the formation of an ionic bond is..

Answer 5

PERMANENT. If the ionic lattice is taken apart by melting, dissolving, or vaporizing, the particles come apart in the form of IONS.

Question 6

Ionic compounds have very high…

Answer 6

melting and boiling points. For example, NaCl melts around 800 degrees C and boils around 1500 degrees C.

Question 7

Ionic compounds tend to be…

Answer 7

brittle solids that dissolve readily in water.

Question 8

The presence of mobile ions allows for…

Answer 8

electric current to be conducted by ionic liquids and solutions.

Question 9

The process of gaining or losing electrons..

Answer 9

completely changes the chemical properties of the substances involved.
