Properties Of Ionic, Covalent And Metallic Bonds Flashcards
When do ionic compounds conduct electricity?
When in liquid form
What form are usually polymers in and why?
Usually solid, they have many weak forces between molecules so they have higher melting point
What are examples of giant covalent structures?
Diamond, graphite, silicon dioxide (SiO2)
Which giant covalent structures conduct electricity and what do they all have in common (b/m point)
Diamond and silicon dioxide do not conduct electricity but graphite does
They all have very high m/b points
What are two structures covalent bond are found in?
Simple molecular and giant
Why can graphite conduct electricity?
It has delocalised electrons
What is meant by “simple” in covalent bonds?
The name of a type of structure contain a small amount of atoms joined together by covalent bonds
