WebAnswer (1 of 5): Just like carbon, it can have +4 or -4, as it can either lose 4 electrons (+4) or gain 4 electrons (-4) (They are both in group 4, C is period 2, Si is period 3). If you have Carbon tetrachloride (a.k.a. Tetrachloromethane), the Carbon would be +4, as Chlorine is more electroneg... WebJuan Ramos. 4, 12월 2024 Last Updated: 14, 3월 2024.
