Question
Atoms of materials that are good conductors of electricity have
no electrons; thus, any that are given to them are easy to move about.
only electrons, and so these electrons are easily moved.
mostly protons; thus, the negative charges jump easily from atom to atom.
outer electrons which are loosely bound and thus easily moved.
The best electrically conducting elements are located __________ in the periodic table
in the last two columns
in the middle columns
in the first two rows
on the left side or in the transition regions
a.no electrons; thus, any that are given to them are easy to move about.
b.only electrons, and so these electrons are easily moved.
c.mostly protons; thus, the negative charges jump easily from atom to atom.
d.outer electrons which are loosely bound and thus easily moved.
Explanation / Answer
If electrons bounds strongly to atoms then the material will not conduct electricty. For a good conductor the outer most electrons must be losely bound.
Therefore correct option is "d" [outer electrons which are loosely bound and thus easily moved]
For second question correct answer is option "d" [on the left side or in the transition regions]. Because in this regions atoms will lose electrons.
