Why is a crystal of Strontium chloride described as an extended structure?
olchik [2.2K]

Answer:

Explanation:

Chloride is described as an extended structure because its atoms are arranged following an endless repeating pattern and are of distinct ratio

Crystals and polymers mostly form extended structures as seen in the formation of sodium chloride whereby the ions in the compound are arranged following a repeating pattern. ( i.e. has a giant ionic structure ).

Chloride is a considered an extended structure because in sodium chloride it forms an unending repeated pattern of ions which makes it a perfect example of an extended structure.

Hence we can conclude that Chloride can be described as an extended structure because its atoms are arranged following a repeating pattern and are of distinct ratio.
