Antimony is graphically represented by the Eye of Horus, a symbol of royal power, good health, and protection from ancient Egypt[1]. It also indicates the use of antimony sulfide as eye makeup[1]. It is stable in air and water, being slightly oxidized by air and insoluble in water[2]...
Antimony, a metallic element belonging to the nitrogen group (Group 15 [Va] of the periodic table). Antimony exists in many allotropic forms. It is a lustrous silvery bluish white solid that is very brittle and has a flaky texture. It occurs chiefly as t
The chart below summarizes the properties of antimony as would be shown on a periodic table. Atomic Number (Number of Protons) 51 Atomic Symbol Sb Atomic Mass (Mass of Protons, Neutrons, and Electrons) 121.76 Antimony is stable at room temperature and is usually found chemically bound to ...
It is likely that the Roman author Pliny used the name stibium in the first century AD. We get the modern element symbol for antimony, Sb, from the word stibium. According to Pliny, the mineral stibnite was found most commonly among silver ores. ...
