      Lithium and chromium are metals.

      Which statement about the properties of these elements is correct?

      • Lithium and chromium react vigorously with water in an exothermic reaction.

      • Lithium and chromium have a similar melting point because their atoms are arranged in a metallic lattice.

      • Lithium can form coloured compounds because it can have more than one oxidation state.

      • Chromium can form coloured compounds because it can have more than one oxidation state.

      The early Periodic table was used to classify the known elements and was used to predict the properties of the elements that had not yet been discovered.

      Which row correctly describes how this was possible?

      • Elements in the same Period displayed similar properties.

      • The arrangement of the known elements provided trends in behaviour which was used to make predictions about the unknown elements.

      • Elements in different Groups displayed similar properties.

      • The unknown elements were used to fill the gaps in the original Periodic table and were placed according to their physical properties.

        As you move down a group on the Periodic table the elements become more metallic in character.

        Which statement explains this observation?

        • Electrons are more easily gained due to increasing atomic radius.

        • Electrons are more easily lost due to increasing atomic radius.

        • The elements are heavier due to the atomic number increasing as you move down a group.

        • The elements are heavier due to the mass number increasing as you move down a group.
