WebCatenation is the characteristic property of carbon but in silicon, this tendency is less pronounced. Because of the greater C−C bond energy than Si−Si bond energy … WebSI code: one 5-credit course or equivalent. Courses that carry the SI GE designation teach students about the essential role of observation, hypothesis, experimentation and measurement in the physical, social, life, or technological sciences. Students should acquire key concepts, facts, and theories relevant to the scientific method.
