Would you expect carbon and silicon to have similar properties?

Yes, they are both classified as non-metals and are located in Group 14.


Why carbon form multiple bonds while silicon can not?

You are mistaken in your question. Silion does form multiple bonds. Glass, for example, is a silica-derived formation as is sand; both include silicon dioxide which has multiple bonds.


Carbon belongs to what element family?

Why is silicon considered a semi metal?

silicon is a mettaloid because it has both properties of metals and non-metals such as: it is a lusturous element like metals it is electronegative like non-metals it is used as a semi -conductor


Is silicon a solid or liquid?

Silicon (Si) is solid at room temperature. Its melting point is 1414°C (2577°F).Silicone is a polymer made from silicon with carbon, oxygen, hydrogen. It is commonly used in breast implants, insulations, cookware, lubrications, sealants, and adhesives. Depending on its use and form, it can both be solid or liquid at room temperature (but never a gas). Some of its more common forms are silicone oil, silicone grease, silicon rubber, and silicone resin.
