Strontium chloride (SCI) is an ionic compound composed of strontium and chlorine atoms. The strontium and chlorine atoms are arranged in a three-dimensional lattice, with each atom connected to its nearest neighbors. This arrangement of atoms is known as an extended structure, as it extends in all directions. This extended structure gives SCI its unique properties, such as its high melting point and solubility in water.
