B (boron, 5)
Si (silicon, 14)
Ge (germanium, 32)
As (arsenic, 33)
Se (Antimony, 51)
Te (Tellurium, 52)
Po (Polonium, 84)
The question if polonium is a metalloid is disputed; many chemists consider polonium as a metal.
Born (B) or Silicon (Si)
Dmitri Mendeleev was a Russian inventor and chemist. He is perhaps best known for his version of the periodic table. This helped him predict properties of elements which had not yet been discovered at that time.

Dmitri Mendeleev was a chemist who is best known for being the first one to sort and set up the Periodic Table of Elements.
Elements in the middle of the periodic table are metals, and they are probably best categorized as transition elements.
Rhodium is a transition element in the periodic table with atomic number 45. Best used in perparing alloys.
Boron (B) or Silicon (Si)
Best known for creating the periodic table of elements. The periodic may also be used now.
Periodic table of elements.
The horizontal rows on the periodic table are periods.

been at the top of the periodic table and at the bottom has nothing to do with electrical properties , it has to do with the atomic wheights and numbers. copper is the best coductor in the periodic table.

The best known tear gas is "CS" gas- this contains carbon, hydrogen, nitrogen and chlorine.

Depends on how you are judging the metals.
