reactivity of metals

Cards (18)

  • ores?

    naturally occurring solid materials from which metals can be extracted economically
  • oxidation?
    oxygen is gained and electrons are lost
  • reduction?
    oxygen is lost and electrons are gained
  • metals + acids=?
    salt + hydrogen
  • metals + oxygen=?
    metal oxide
  • metals that react with water?
    group one alkaline metals
  • metals + water=?
    metal hydroxide + hydrogen
  • reactivity series?
    list of elements in order of their reactivity
  • what is a displacement reaction?
    in a displacement reaction, the more reactive element (swaps with/ displaces) the less reactive element in a compound
  • how do we know the reactivity of a metal?
    by its ability to form positive ions
  • why are some metals not found in their native state?
    very reactive metals are always found reacted with other elements to form ores
  • how can we extract metals from compounds?
    by displacing them with a more reactive element
  • copper?

    a metal that does not react with water or an acid
  • redox?
    reaction where oxidation and reduction takes place
  • chlorides?

    salts produced from hydrochloric acid
  • sulphates?
    salts produced from sulfuric acid
  • nitrates?

    salts produced from nitric acid
  • hydrogen?

    gas formed when a metal reacts with water and/or acid
