Bonding

Question 1

What substances have ionic bonding

Answer 1

metals and non-metals (involves electron transfer)

Question 2

What type of particle does ionic bonding contain

Answer 2

ions = giant lattice structure

Question 3

How are particles bonded together in ionic bonding

Answer 3

strong electrostatic attraction between oppositely charged ions

Question 4

What are the typical properties (melting and boiling point) of ionic bonding

Answer 4

high melting/boiling point as it requires a large amount of energy to overcome the strong electrostatic attractions between oppositely charged ions

Question 5

Electrical conductivity of ionic bonding

Answer 5

it conducts electricity when molten or aqueous as the ions are free to move and carry a charge

Question 6

Solubility of ionic bonding in water

Answer 6

mostly soluble in water as it forms strong interactions with water molecules

Question 7

What substances have metallic bonding

Answer 7

metals

Question 8

What type of particle does metallic bonding contain

Answer 8

positive metal ion and delocalised electrons = giant lattice

Question 9

How are particles bonded together in metallic bonding

Answer 9

strong electrostatic attraction between positive metal ion and sea of delocalised electrons

Question 10

What are the typical properties (melting and boiling point) of metallic bonding

Answer 10

high melting/boiling point as it requires a large amount of energy to overcome the strong electrostatic attractions between positive metal ions and sea of delocalised electrons

Question 11

Electrical conductivity of metallic bonding

Answer 11

conducts electricity as the electrons are free to move and carry a charge

Question 12

Solubility of metallic bonding in water

Answer 12

insoluble in water as it doesn’t from strong interactions with water molecules

Question 13

What substances have giant covalent bonding

Answer 13

non-metals

Question 14

What type of particle does giant covalent bonding contain

Answer 14

many atoms covalently bonded - giant lattice

Question 15

How are particles bonded together in giant covalent bonding

Answer 15

strong covalent bonds between atoms (shared pair of electrons)

Question 16

What are the typical properties (melting and boiling point) of giant covalent bonding

Answer 16

high melting/boiling point as it requires lots of energy to break strong covalent bonds between atoms

Question 17

Electrical conductivity of giant covalent bonding

Answer 17

doesn’t conduct electricity (except graphite) as it has no free ions/delocalised electrons to carry a charge

Question 18

Solubility of giant covalent bonding in water

Answer 18

insoluble in water as it doesn’t form strong interactions with water molecules

Question 19

What substances have simple molecular covalent bonding

Answer 19

non-metals (small groups of atoms)

Question 20

What type of particle does simple molecular covalent bonding contain

Answer 20

small groups of atoms covalently bonded = simple structure

Question 21

How are particles bonded together in simple molecular covalent bonding

Answer 21

weak intermolecular forces holding molecules together

Question 22

What are the typical properties (melting and boiling point) of simple molecular covalent bonding

Answer 22

low melting/boiling point as not much energy is required to break the weak intermolecular forces

Question 23

Electrical conductivity of simple molecular covalent bonding

Answer 23

doesn’t conduct electricity as there are no ions or delocalised electrons free to move and carry a charge

Question 24

Solubility of simple molecular covalent bonding in water

Answer 24

sometimes soluble in water as it depends on if they can form hydrogen bonds with water
