1) Why do atoms form ions? a) To make sure they have the same number of protons as neutrons. b) To make their atomic mass the same as their atomic number. c) To reduce the number of electron shells d) To produce a full outer shell of electrons. 2) How do metals form ions? a) By gaining an electron from a non metal. b) By losing a proton to another metal. c) By losing one (or more) electrons to a non - metal. d) By gaining a proton from another atom. 3) How do non metals form ions? a) By gaining electron(s) from a metal. b) By losing a proton to another non metal. c) By losing one (or more) electrons to a metal. d) By gaining a proton from another atom. 4) What do we call positive ions? a) Dogions b) Anions c) Cations d) Thions 5) What do we call negative ions? a) Anions b) Cations c) Dogions d) Protons 6) What holds ions together? a) A Sea of Electrons b) A shared pair of electrons c) Electrostatic attraction between ions. d) Fairy dust. 7) What phrase best describes an ionic solid? a) A regular lattice of cations surrounded by a sea of delocalised electrons. b) A regular lattice of anaions surrounded by a sea of protons. c) A regular lattice of Anions and Cations. d) An amorphous arrangement of ions with no recognisable order. 8) Ionic compounds are malleable? a) True b) False 9) Ionic compounds have high melting points because..... a) They are made from very heavy particles which are difficult to get moving. b) The bonds between ions are very strong and need a great deal of energy to break them. c) The ions are very cold. d) The layers of ions break off in sheets. 10) Ionic compounds do not conduct as solids because......... a) They have no charged particles. b) The free electrons carry electricity away. c) The cations are too heavy. d) The ions cannot move in order to carry the current.
