A solid substance is an excellent conductor of electricity. the chemical bonds in this substances are most likely
1. ionic, because the valance electrons are shared between atoms
2. ionic, because the valance electrons are mobile
3. metallic, because the valance electrons are stationary
4. metallic, because the valance electrons are mobile

Answer;

-4. metallic, because the valance electrons are mobile

Explanation;

-Electrical conductivity in metals is a result of the movement of electrically charged particles.The atoms of metal elements are characterized by the presence of valence electrons (electrons in the outer shell of an atom) that are free to move about.

-Therefore; Metallic elements such as sodium and potassium conducts electricity in solid form due to the presence of delocalized valence electrons. These electrons can move freely within the structure of a metal when an electric current is applied.
