The electron sea is responsible for which of the following properties? a. all of these b. malleable c. ductile d. conducting electricity and heat

D.Conducting electricity and heat

Explanation:

Metal : It is defined as that substance which is good conductor of electricity and heat. Metal have  ductile and malleable property.In metal, atoms are held together by metallic bonds .The valence electrons from s and p orbital are delocalised and they form sea of electrons that surround the positively charged nuclei of the interacting metal ion.Then , the electrons are freely move throughout the space between atomic nuclei.

Due to availability of free  electrons, metal conduct electricity and heat.

Therefore, the electron sea is responsible for conducting electricity and heat .
