Which of these is not a property of metals? They are all lustrous They are all magnetic They all conduct electricity and heat Their oxides are always bases They all have a high density They always form positive ions.
This element burns in oxygen with a bright orange flame. It is… sodium potassium sulphur lithium
Metals can….. Gain electrons to become negative ions. Gain electrons to become positive ions. Lose electrons to become positive ions. Lose electrons to become negative ions.
Universal indicator is unusual because… It produces a range of colours It works best in alkalis. It changes colour at pH4
All metal oxides are….. Hydroxides SaltsBases Alkalis
This metal burning is… Calcium Potassium Lithium Sodium
Neutralisation reactions always produce a metal salt and water alkalis hydrogen carbon dioxide
