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).

d.) circle motion requires a force to give it a centripetal acceleration.

no, the red giant is the hottest with 2.00.000.000 degrees celsius. while the white dwarf only 25,000 degrees celsius.
