What is the noble gas configuration for silicon?

The noble gas configuration of Silicon is [Ne] 3s23p2. The full electron configuration of silicon is 1s22s22p63s23p2. To find its noble gas shorthand, look at the full electron configuration and see how many filled shells there are. For silicon, all but the outermost shell is filled. So the number of filled shells is 2. Now look at the periodic table and find the noble gas at the end of the period the same as the number of filled shells. The noble gas at the end of Period 2 is neon, Ne.

chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances. these processes are called chemical reactions and, in general, are not reversible except by further chemical reactions. some reactions produce heat and are called exothermic reactions and others may require heat to enable the reaction to occur, which are called endothermic reactions. understanding chemical changes is a major part of the science of chemistry.
