			'''Adjacent silicon period two nonmetallides:'''
			* [[Silicon nitride]] … nitrogen right next to carbon and still in same group, still high hardness
			* [[Polymorphs of silicon dioxide]] … most are near Mohs 5 quartz like, two are superdense superhard zero pressure metastable polymorphs
			* [[Silicon fluoride]] … SiF<sub>4</sub> corrosive toxic gas at room temperature
