A period 3 element is one of the chemical elements in the third row (or period) of the periodic table of the chemical elements.The periodic table is laid out in rows to illustrate recurring (periodic) trends in the chemical behavior of the elements as their atomic number increases: a new row is begun when chemical behavior begins to repeat, meaning that elements with similar behavior fall into ...
It melts at 631 °C. Antimony is a semimetal with an electrical conductivity of around 3.1 × 10 4 S•cm −1 [363] and a band overlap of 0.16 eV. [337] [n 39] Liquid antimony is a metallic conductor with an electrical conductivity of around 5.3 × 10 4 S•cm −1. [365] Most of the chemistry of antimony is characteristic of a nonmetal. [366]
Antimony has a density of 6.697 g/cm 3, and is moderately hard (MH 3.0; about the same as copper). It has a rhombohedral crystalline structure (CN 3). Antimony melts at 630.63 °C and boils at 1635 °C. It is a semimetal, with an electrical conductivity of around 3.1 × 10 4 S•cm −1 and a band overlap of 0.16 eV. Antimony has a moderate ...
Period: period 3: Block ... [3] Thermal conductivity: 149 W/(m⋅K) ... silicon's electrical conductivity increases with higher temperatures.
Antimony is a soft (MH 3.0) and brittle semi-metallic element. It is commonly regarded as a metalloid, or by some other authors as either a metal or a non-metal. It exhibits poor electrical conductivity which, like a metal, decreases with temperature. It has a relatively open and partially covalent crystalline structure (BCN 3+3).
The electrical conductivity of graphite exceeds that of some metals; [n] Selenium can be drawn into a wire; [ 51 ] Radon is the most metallic of the noble gases and begins to show some cationic behavior, which is unusual for a nonmetal; [ 96 ] and
