Bonding Flashcards
What substances have ionic bonding
metals and non-metals (involves electron transfer)
What type of particle does ionic bonding contain
ions = giant lattice structure
How are particles bonded together in ionic bonding
strong electrostatic attraction between oppositely charged ions
What are the typical properties (melting and boiling point) of ionic bonding
high melting/boiling point as it requires a large amount of energy to overcome the strong electrostatic attractions between oppositely charged ions
Electrical conductivity of ionic bonding
it conducts electricity when molten or aqueous as the ions are free to move and carry a charge
Solubility of ionic bonding in water
mostly soluble in water as it forms strong interactions with water molecules
What substances have metallic bonding
metals
What type of particle does metallic bonding contain
positive metal ion and delocalised electrons = giant lattice
How are particles bonded together in metallic bonding
strong electrostatic attraction between positive metal ion and sea of delocalised electrons
What are the typical properties (melting and boiling point) of metallic bonding
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
Electrical conductivity of metallic bonding
conducts electricity as the electrons are free to move and carry a charge
Solubility of metallic bonding in water
insoluble in water as it doesn’t from strong interactions with water molecules
What substances have giant covalent bonding
non-metals
What type of particle does giant covalent bonding contain
many atoms covalently bonded - giant lattice
How are particles bonded together in giant covalent bonding
strong covalent bonds between atoms (shared pair of electrons)
What are the typical properties (melting and boiling point) of giant covalent bonding
high melting/boiling point as it requires lots of energy to break strong covalent bonds between atoms
Electrical conductivity of giant covalent bonding
doesn’t conduct electricity (except graphite) as it has no free ions/delocalised electrons to carry a charge
Solubility of giant covalent bonding in water
insoluble in water as it doesn’t form strong interactions with water molecules
What substances have simple molecular covalent bonding
non-metals (small groups of atoms)
What type of particle does simple molecular covalent bonding contain
small groups of atoms covalently bonded = simple structure
How are particles bonded together in simple molecular covalent bonding
weak intermolecular forces holding molecules together
What are the typical properties (melting and boiling point) of simple molecular covalent bonding
low melting/boiling point as not much energy is required to break the weak intermolecular forces
Electrical conductivity of simple molecular covalent bonding
doesn’t conduct electricity as there are no ions or delocalised electrons free to move and carry a charge
Solubility of simple molecular covalent bonding in water
sometimes soluble in water as it depends on if they can form hydrogen bonds with water
