what is metallic lattice

Asked by rkjsgr | 17th Aug, 2010, 12:00: AM

Expert Answer:

In metals the valence electrons are not tightly held by the nucleus as a result they are mobile or free.
 

For example Lithium metal. Its electronic configuration is 2,1. It has 1 valence electron and after loosing it the remaining Li+ s called positive kernel of lithium

There is a strong electrical force of attraction between these mobile electrons (-) and the 'immobile' positive metal ions (+)  known as positive kernel.So the positively charged kernels of metal atoms are arranged in a regular fashion surrounded by loosely held valence electrons. This arrangement is called  a metallic lattice
