Antimony is a gray-colored lustrous metalloid that is found mainly as Sb2S3. Let us focus on the chemical properties of antimony. Antimony is refined industrially from stibnite by roasting and followed by reduction in presence of carbon or direct reduction of stibnite with iron. It is a hard, brittle metalloid compound. Elemental antimony possesses a … Read more
Arsenic is a metalloid, and it is found in minerals in combination with sulfur and metals. Let us explain the chemical properties of arsenic in brief. Arsenic is a silver-grey, brittle, crystalline, and naturally occurring solid which is widely found in the earth’s crust. It is a common n-type dopant in semiconductors. It burns rapidly … Read more
Mercury is a liquid metal in the periodic table. Let us explain about facts related to mercury. Mercury is a heavy, shiny and silvery liquid metallic substance. It has a rhombohedral crystal structure. Mercury does not participate in the reaction with most acids but it reacts with hydrogen sulfide (H2S). Maximum metals (except iron) are … Read more
Cadmium is a silvery-white and soft metal that belongs to the group of zinc and mercury. Let us discuss the chemical properties of cadmium. Cadmium is found as a minor component or impurity in zinc ores and is obtained as the by-product of zinc production. This soft, malleable, and ductile metal makes up about 0.1 … Read more
Tungsten is a chemical element that can be found naturally on the earth’s crust, and it forms compounds with other elements. Let us explore its chemical properties of it in brief. Tungsten is a hard and brittle steel-grey metal. But pure monocrystalline tungsten becomes malleable enough and can be used easily. It has high tensile … Read more
Molybdenum does not occur in nature as a free metal, it is obtained in minerals with different oxidation states. Let us discuss the chemical properties of molybdenum. Molybdenum is a silvery grey metal having a very high melting point (sixth highest on the periodic table). It can form stable and hard carbides in alloys. Most … Read more

Na2SO3 is an ionic compound with hexagonal monoclinic crystal structure. The anhydrous Na2SO3 has density 2.633 g/cm3 whereas the heptahydrate Na2SO3 possesses a density 1.561 g/cm3. Though it … Read more
HgBr2 or mercury bromide is a solid white coloured inorganic compound. Let us discuss the lewis structure and some properties of HgBr2 briefly. HgBr2 has a linear structure with a molecular mass 340.41 g/mol. It is prepared by the reaction between metallic mercury and bromine. It is used as a reagent of Koenigs-Knorr reaction which … Read more
Ch2I2 is a chemical compound that consists of two iodine atoms bonded to a central carbon atom, with two hydrogen atoms attached to the carbon. The Lewis structure of Ch2I2 helps us understand the arrangement of these atoms and their bonding patterns. Lewis structures are diagrams that show the valence electrons of atoms and how … Read more
The Methyl iodide (CH3I) consists of a central carbon (C) atom with 4 valence electrons, bonded to three hydrogen (H) atoms and one iodine (I) atom. Each H contributes 1 electron, and I contributes 7, totaling 8 bonding electrons. The C-I bond is polar due to the electronegativity difference (C: 2.55, I: 2.66), resulting in … Read more
