The appropriate answer is a. it's valence electrons are held tightly within the crystal structure. Metals are good conductors because they share electrons and so they are free to move about enabling it to be a good conductor. Any substance that has electrons tightly held within bonds will not be good conductors. If the structure of pure silicon had its valence electrons held loosely by a positive nucleus then it would be able to conduct.

Why must there be two chlorine atoms for every one calcium atom

Nady [450]

Answer:

There must be two Chlorine atoms for every one Calcium atom in order to fulfill Chlorine's octet rule and pair Calcium's unpaired electrons.

Explanation:

Calcium has two unpaired electrons in its Lewis dot structure, while Chlorine has one unpaired electron.

So why can't we just make a double bond for one Chlorine?

Chlorine has seven valence electrons, so once it shares electrons with Calcium, the octet rule is accomplished, and no more pairs can be made.
