May 02, 2017 · Mendelev also created the atomic data which made him discovered what is called the Periodic Law. In purpose for increasing atomic mass, he was arranged the elements. From his atom experiment, he discovered the properties was repeated. On his table, periodically the properties were repeated. Because of this, this system is known as periodic table.

Arsenic appears in three allotropic forms: yellow, black and grey; the stable form is a silver-gray, brittle crystalline solid. It tarnishes rapidly in air, and at high temperatures burns forming a white cloud of arsenic trioxide. Arsenic is a member of group Va of the periodic table, which combines readily with many elements.

Seeing chemical elements arranged in the modern periodic table is as familiar as seeing a map of the world, but it was not always so obvious.
