Name 2 properties of non-metals

low melting points, not usually shiny, brittle, poor conductor of electricity, low density

What does 'poly' mean

many

Do metals have a high or low melting points and why?

high, due to the oppositely charged electrons and metal ions

Is a buckyball a giant or simple covalent structure

Simple

Where is silica most commonly found

Sand

True or false : Valency is the number of electrons needed to complete the outer shell

true

What is a synthetic polymer and why are they difficult to dispose of?

man made, because they are unreactive

Name 1 example of a natural polymer

cellulose, DNA, protein, keratin

Name all 4 allotropes of carbon

graphene, fullerenes, graphite, diamond

How many electrons does electrons have

8

Draw a diagram of a lattice of metals and label it

What is the most stable group on the periodic table and why?

Noble gases ( they have full outer shells )

Which allotrope of carbon cannot conduct electricity and why?

Diamond, because there's no free electrons

Which allotrope of carbon has 4 bonds to each carbon atom

diamond

Is graphene a giant or simple covalent structure

giant

What is the periodic table made up of?

Elements

Is a buckyball a giant or simple covalent structure

Simple

What does malleable mean?

able to be pressed/hammered into shape without breaking

Name 2 properties of metals

high melting points, shiny, good conductor of electricity, malleable, high density

Where is silica most commonly found

Sand

True or false : graphite is used in pencils

true

What does 'mono' mean

one

Name 2 properties of a covalent bond

- the bond is very strong - the intermolecular bond between molecules is weak - low melting and boiling points

Which bond occurs between two non-metals

covalent bond

How do you work out how many neutrons are in an atom

top number - bottom number

Which bond occurs between a non-metal atom and a metal atom

ionic bonding

In metallic bonding, what happens to the electrons on the outer shells?

they are lost from the atoms and form a sea of delocalised electrons

Show the covalent bond between 2 hydrogen atoms

Name 2 properties of ionic bonding

- strong electrostatic force - high melting and boiling points - soluble in water - only conduct electricity if a liquid or dissolved in water

Draw a sodium (Na) atom.

True or False : if its a thermal conductor it allows electricity to flow through the material

false - it allows heat

Show the ionic bond between sodium + chlorine and name the ions
