Types of Bonding and Properties - exam practice

are held together by forces of attraction between positive and negative ions

are held together by electrostatic forces

consist of lattices containing only positive ions

consist of giant structures of atoms

a group of atoms bonded by ionic bonds

a group of atoms bonded by covalent bonds

a group of ions bonded by covalent bonds

a group of atoms bonded by metallic bonds

metal atoms are arranged in a regular lattice

metal ions are very close to each other

metal ions are free to move through the lattice

electrons are free to move through the lattice

NH₃

OH^-

H₂O

H₃O⁺

sodium atoms are smaller than magnesium atoms

sodium ions have a larger charge density than magnesium ions

the repulsion between the ions in sodium is less than in magnesium

the number of delocalised electrons per atom is fewer in sodium than in magnesium

the ions are the same size

the attraction between two sodium ions is greater than the repulsion between two chloride ions

each sodium ion is surrounded by six chloride ions

there are more sodium ions than chloride ions
