Bismuth Trichloride Formula: Bismuth, denoted by the symbol Bi and It holds an atomic number of 83. It is a dense, silvery metal with a subtle pink color. It stands out as the most diamagnetic among all metallic elements. The yellow pigment known as bismuth oxide finds widespread application in cosmetics and paints, while its compounds have been used as medicinal agents, falling within the category of antibacterial medications. Elemental bismuth itself is non-toxic. However, caution is necessary when dealing with bismuth salts, which can lead to toxic effects.
Chlorine represented by the symbol Cl and with an atomic number of 17. It exists as a corrosive greenish-yellow gas that is known for its toxicity and due to toxicity it causes irritation to both the eyes and the respiratory system. It ranks as the second lightest element within the halogen group, sandwiched between fluorine and bromine in the periodic table. Chlorine serves as an effective bleaching agent and was initially discovered by Carl Wilhelm Scheele in the year 1774.

Structural aspects of Bismuth trichloride, we can establish its Lewis structure. Bismuth is endowed with five valence electrons, while chlorine carries seven valence electrons. Considering the presence of three chlorine atoms, the cumulative valence electrons amount to 5 + 7(3) = 26. To construct the Lewis structure, bismuth is placed at the central position, and the three chlorine atoms are arranged around it. This results in a structural configuration as illustrated below.
