Comparison of physical properties of elements in group 2 and group 14​

Group 14 elements are less electropositive than group 13 owing to their small size and high ionization enthalpy. Down the group, the metallic character increases. C and Si are non-metals, Ge a metalloid, and Sn and Pb are soft metals with low melting points.

Group 2A (or IIA) of the periodic table are the alkaline earth metals: beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra).

c (diamond),

sio2 (quartz)

what is the question here. i think you messed up.
