Bismuth is a chemical element with the symbol Its atomic number is 83. It is a high-density, silvery, pink-tinged metal. It is the most diamagnetic of all metals. Bismuth oxide is a yellow pigment that is widely used for cosmetics and paints. Its compounds have been used extensively as medicines. It comes under a class of medications called antibacterial agents. Elemental bismuth is nontoxic but bismuth salts can cause toxicity.
Chlorine is a chemical element with the symbol Its atomic number is 17. It is a toxic corrosive greenish-yellow gas that is irritating to the eyes and to the respiratory system. It is the second lightest of the halogens it appears between fluorine and bromine in the periodic table. Chlorine is used as a bleaching agent. It was discovered by Carl Wilhelm Scheele in 1774.
Bismuth Trichloride
Bismuth Trichloride is an inorganic compound with the chemical formula BiCl3. It is a covalent compound. It is a colorless hygroscopic solid. It is also known as trichloro bismuth and bismuth chloride. It has Bismuth and chloride ions in it. It is obtained by reacting bismuth with chlorine. It’s a decent source of bismuth and is used to form other bismuth compounds.
Structure Of Bismuth trichloride
Let’s do the Lewis structure for BiCl3.Bismuth has 5 valance electrons and chlorine has 7 valance electrons here we have 3 chlorine atoms so total valance electrons are 5+7(3) = 26. We’ll put Boron at the center and then let’s put the Chlorines around it, there are three of them. The structure looks like this below
