properties of ionic compounds and small molecules

what are regular structures of ionic compounds?

giant ionic lattices

what are in the giant ionic lattices?

strong electrostatic forces of attraction in all directions between oppositely charged ions

what are the boiling points in ionic compounds?

high

what are the melting points in ionic compounds?

high

why do ionic compounds have high melting & boiling points?

a lot of energy is required to break the many strong bonds

what happens when ionic compounds are melted or dissolved in water?

they conduct electricity because the ions are free to move and carry current

why can’t ionic compounds conduct electricity when solid?

the ions are fixed in place

what substances are made of small molecules usually?

gases or liquids with low boiling and melting points

what are the small molecules’ intermolecular forces like?

weak

how are the small molecules’ intermolecular forces broken?

boiling or melting

how do the intermolecular forces increase?

with the size of the molecules

do small molecules conduct electricity?

no because they don’t have an overall electric charge
