Bonding

Question 1

What is ionic bonding

Answer 1

When metals react with non-metals, electrons are transferred from the metal atoms to the non-metal atoms, forming ions.

Question 2

What is covalent bonding

Answer 2

forms when two non-metal atoms share a pair of electrons

Question 3

What is metallic bonding

Answer 3

electrostatic attraction between positive metal ions and delocalised electrons

Question 4

Properties of ionic bonding

Answer 4

high melting and boiling points, poor conductivity in solid state, and high conductivity in aqueous solutions

Question 5

Properties of metallic bonding

Answer 5

their shiny lustre, their malleability, and their conductivities for heat and electricity

Question 6

The properties of graphite as a giant covalent structure

Answer 6

each carbon atom is joined to three other carbon atoms by covalent bonds which leaves one electron to become delocalised . the carbon atoms form layers with a hexagonal arrangement of atoms. the layers have weak forces between them. This makes the graphite slide off in layers which makes it useful for pencils

Question 7

Properties of diamond giant covalent structures

Answer 7

each carbon atom is joined to four other carbon atoms by strong covalent bonds. the carbon atoms form a regular tetrahedral network structure. there are no free electrons. This means the diamond is very hard . Which makes it useful for things such as drill bits

Question 8

Properties of fullerene giant covalent structures

Answer 8

borderless, uncharged, has no boundaries, no dangling bonds, and no unpaired electrons. This makes fullerene have high melting points and boiling points.

Question 9

Does diamond conduct electricity

Answer 9

Diamond has no free electrons and therefore cannot conduct electricity
