Question

Answer 1

Most of the elements on the periodic table are metals...generally speaking...metals occur on the left side of the periodic table, and non-metals occur on the right side of the periodic table... 

...check out the periodic table locate at: http://www.elementsdatabase.com/ 
look at the second colored periodic table...take a look at the key for this table...notice that the non-metals are colored white or red...all other elements would therefore be metals...
