2.3 Flashcards
What are ionic compounds made up of
Giant lattice structures
High melting and boiling points bc of
Strong electrostatic forces acting between oppositely charged ions
The greater charge of the ion
The stronger the electrostatic force and the higher the melting point
What does there need to be for and electrical current to flow
Freely moving charged particles such as electrons or ions present
Ionic compounds can conduct electricity in the what state or solution
Molten state or solution
Why can they not conduct electricity in the solid state
The ions are Fixed positions within the lattice and unable to Moo e
What are small molecules
ompounds made up of molecules that contain just a few atoms covalently bonded together
What do small molecules have
Low melting and boiling point because of weak intermolecular forces
Why are covalent company’s insoluble in water
Tend to be non polar and dissolve in organic solvents
How good are small molecules conductors of electricity
Poor conductors no free ions or electrons to carry the charge
What are small molecules made up of
Covalent bonds joining atoms, intermolecular forces acting between neighboring molecules
What are small molecules at room temp
Gases or liquids
