Title: Structure and general properties of nonmetals
Post by: Win,odd Dhamnekar on March 16, 2022, 04:45:11 AM

Carbon forms a number of allotropes, two of which are graphite and diamond. Silicon has a diamond structure. Why is there no allotrope of silicon with a graphite structure?

Well, first: you're incorrect - there is a graphene analog for silicon (https://en.wikipedia.org/wiki/Silicene), although the two have important electronic and structural differences. Did you read my answer to you in your other recent thread (https://www.chemicalforums.com/index.php?topic=111137.0), about phosphorous vs nitrogen? Similar logic applies here.
