Sodium is a chemical element with syol Na (from Latin natrium) and atomic nuer 11. It is a soft, silvery-white, highly reactive metal. Sodium is an alkali metal, being in group 1 of the periodic table, because it has a single electron in its outer shell that it readily donates, creating a positively charged atom—the Na+ ion.

Why silicon counts among metalloids? - Find 6 …

Look,Silicon has 4 electrons in its outer orbitals and to attain stable state it can DONATE all its electrons like a METAL or it can ACCEPT 4 electrons like NON METALS!! Also,it shows both the properties of a metal and a non-metal and it is used as a Semiconductor!! So,it is called a metalloid or a semi-metal!!! Hope it will help you!
