Question

What is reason behind shining of metal / Nonmetals .
★ Spam deleted on spot ★

Answer 1

Basically metal have 1,2 or three electrons in their outermost shell and create metallic bond between themselves, where the electrons, instead of belonging to its own nucleus, roam around between the whole metallic body. Whereas, non metals have 4 or more electrons on their outermost shell and create covalent bond,so there is no scope for existence of free electrons. SO, they are not shiny or, lustrous.
