As the atomic numbers of the elements in column iia increase, the size of the atoms generally:
a. increase stay the same
b. cannot tell
c. decrease
d. varies

as the atomic numbers of the elements in column iia increase, the size of the atoms generally: increase stay the same- a.

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.
