metallic elements are found in the center of the periodic table, and nonmetallic elements are anywhere but the middle...
The number of electrons to be gained or lost is what differientiates metallic and non-metallic elements on the periodic table at a subatomic level.
It is periodic.
On the left side of the periodic table.
bottom left
no it isn't you can check on the periodic table
yes, there are far more metallic elements than nonmetals.
iron
Tin is metallic because the shielding of electrons is so much that the electrostatic force is weak and so Tin is metallic. Moreover as we move from right to left in a periodic table and top to bottom along the group the metallic character increases. Hence Sn is metallic.
no, coal is not metallic because it is almost completely composed of carbon, a nonmetallic element that is 6th in the periodic table.
Inert/noble gases
hydrogen
