ionic bonding and structurre Flashcards
What is ionic bonding?
Ionic bonding is the electrostatic attraction between positive and negative ions.
It is a relatively strong attraction.
How are ionic compounds held together?
● They are held together in a giant lattice.
● It’s a regular structure that extends in all directions in a substance.
● Electrostatic attraction between positive and negative ions holds the structure together.
State properties of ionic substances.
● High melting and boiling point (strong electrostatic forces between oppositely charged ions)
● Do not conduct electricity when solid (ions in fixed positions).
● Conduct when molten or dissolved in water - ions are free to move.
What is important when working out a formula of an ionic compound?
Ionic compounds are electrically neutral, i.e. positive and negative charges balance each other.
