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.
