Antimony is a metalloid; its outermost electrons are not free to move in the crystal structure because they are fixed in position in a covalent bond. It has metallic luster but is brittle with no useful mechanical properties.
8 Νοε 2023 · Antimony is stable at normal temperatures, but reacts with oxygen when heated. There are four antimony allotropes known. One of allotropes, metallic antimony, is stable, but the other three are metastable. One of the metastatic forms is explosive antimony and produces a white smoke when drawn with a metal object.It has two stable isotopes.
Element Antimony (Sb), Group 15, Atomic Number 51, p-block, Mass 121.760. Sources, facts, uses, scarcity (SRI), podcasts, alchemical symbols, videos and images.
The physical and chemical properties of antimony and selected antimony compounds are given in Table 4-2. Antimony metal is stable under ordinary conditions. Antimony is a poor conductor of heat and electricity (Li 2011). Antimony forms complex ions with organic and inorganic acids.
Physical Characteristics. Antimony is a shiny grey metalloid. It is a soft element and cannot be used to make hard objects, including coins. There are four allotropic forms of antimony three metastable forms: yellow, black and explosive, and one metallic form that is stable. Chemical Characteristics
Chemical, physical and material properties and data of the chemical element Antimony.
Antimony(III) oxide can exist in various polymorphs, notably valentinite and senarmontite, with different chemical and physical characteristics. The aqueous speciation of antimony may be complex.
