Melting Point of Period 3 Elements - Chemistry Guru
WebSilicon has the highest melting point of any element in period three at 1410 degrees Celsius. This high melting point of silicon is due to its structure, specifically its giant covalent structure. A giant covalent structure is held together by many covalent bonds. WebAs you can see there's a fairly common pattern in both Periods. The melting points rise from Grp 1 to Grp 4. Then there is a huge drop off. Why?
