Arsenic - Wikipedia, the free encyclopedia

2012-11-28 · Arsenic is a chemical element with syol As and atomic nuer 33. Arsenic occurs in many minerals, usually in conjunction with sulfur and metals, and also as a pure elemental crystal. It was first documented by Albertus Magnus in 1250. [5] Arsenic is a metalloid.It can exist in various allotropes, although only the gray form has important use in industry.

Boron | 7440-42-8

Boron is a semimetal, sometimes classed as a metallic or metalloid or even as a nonmetal.It reseles carbon more closely than aluminum. Although it is extremely hard in its purified form—almost as hard asdiamonds—it is more brittle than diamonds, thus limiting its usefulness.
