ionic compounds

How is the structure of ionic compounds

Lattice (a closely packed regular arrangement).

Ionic compounds are giant structures of ions held together in a lattice by electrostatic forces known as ionic bonds

How can ionic compounds be represented

In dot and cross diagrams

3 d models

Ball and stick models -which show different ions and put lines between to show different bonds

What are the properties of ionic compounds

And what is it determined by

Properties

Very high melting and boiling points

Can conduct electricity

Determined by

Melting and boiling points are determined by the strength of the bonds holding substance together. And Ionic compounds there are loads of ionic bonds all of which are very strong to break and all require loads of energy which will only be available at very high temperatures

-Conducting electricity depends on if there are charge particles that can move (can either be ions or elections)

Why can’t ionic compounds conduct electricity when solid

When I want it compounds are in solid form everything is fixed so they can’t conduct electricity. However when they’re melted or dissolved in water, the ions are free to move about and this movement of charge particles allows them to conduct electricity.
