The atomic number of an element is 14. Examine if this element will have metallic properties or not. Give reason to justify your answer.
Answer
Atomic number = 14
Electronic configuration = 2,8,4
The element is Si. Since it has 4 electrons in the outermost shell , it can neither gain nor lose electrons to become stable .
Rather, it shares electrons and forms covalent bonds .
Thus, it has the properties of both metals and nonmetals and so is called metalloid.
