chemistry 2.1 - ionic bonding

Are anions or cations positive?

Cations

What is ionic bonding?

When strong electrostatic attraction holds anions and cations together

How does charge effect ionic bonding?

Greater charge = stronger ionic bond

How does ions size effect ionic bonding?

Smaller ions = can pack closer together = stronger ionic bonds as electrostatic attraction weakens with distance

What are isoelectric ions?

Ions of different atoms with the same number of electrons

What are giant ions lattices?

Ions repeated over and over again in a regular structure

How can you tell ionic binds are strong?

High melting and boiling points

How can you tell the particles in an ionic lattice are charged?

Dissolve in water but not in a non - polar solvent

How can you tell ions in an ionic lattice are in fixed position when solid?

Because they don’t conduct electricity when solid but do when in a liquid

Why are ionic lattices brittle?

The layers can’t slide over each other due to strong repulsion
