Ionic compounds Flashcards
Ions are formed when…
Ions are formed when atoms lose or gain electrons to obtain the stable electron arrangement of a noble gas
metal atoms _____ electrons forming _____ ions and non-metal atoms _____ electrons forming _____ ions.
Gain Lose Positive Negative
metal atoms lose electrons forming positive ions and non-metal atoms gain electrons forming negative ions.
An ionic bond is…
An ionic bond is the electrostatic attraction between positive and negative ions
Structure of an ionic substance
Ionic lattice structure made of oppositely charged ions with each positive ion surrounded by negative ions and each negative ion surrounded by positive ions.
• have high melting and boiling points
• many compounds are soluble in water
• conduct electricity only when molten or in solution
Type of bonding and structure?
Ionic lattice
Conduction in ionic compounds.
What direction do the ions move?
Conduction in ionic compounds can be explained by the movement of ions towards oppositely charged electrodes.
