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]

Acalorimeter is to be calibrated: 51.203 g of water at 55.2 degree c is added to a calorimeter containing 49.783 g of water at 23.5c. after stirring and waiting for the system to equilibrate, the final temperature reached is 37.6 degree c. specific heat capacity of water (s = 4.18 j/g∙degree c). calculate the calorimeter constant. (smδt)warm water = -[(smδt)cold water + (calorimeterδtcold water)]
