There are six elements in group 14 on the periodic table. one of these elements has the symbol uuq, which is a temporary, systematic symbol. this element is now known as flerovium.

66 identify an element in group 14 that is classified as a metalloid. [1]
67 explain, in terms of electron shells, why each successive element in group 14 has a larger atomic radius, as the elements are considered in order of increasing atomic number. [1]
68 state the expected number of valence electrons in an atom of the element flerovium in the ground state. [1]
