Answer 2

Answer:

silicon belongs to 14 group and it has 4 electrons in its valency shell.thus it can attain stable electronic configuration by sharing,gaining,or by loosing four electrons.so silicon is called tetravalent.Cl belongs to 17 group so it has 7 electrons in valency shell it can attain stable configuration by gaining one electron.so Cl is monovalent.
