Silicon is the second most abundant element in the Earth's crust, and its compounds can be as ordinary as beach sand. However, silicon also plays an indispensable role in modern devices such as computers, cell phones, semiconductors, and solar panels. A recent technology incorporates silicon in nanometer-sized particles called quantum dots that act as luminescent labels for pancreatic cancer cells (ACS Nano 2008, 2, 873-878). Identify the electron configuration of a silicon atom. O 1s²2s²2p 3s²3d 103p3 O 1s²2s²2p63p4 O 1s²2s²2p63s²3p² O 1s²2s²2p63s²3p³

Stoichiometry

Stoichiometry is a chemical division that evaluates the quantitative content of the chemical process with the help of the reacting molecules or products taking part in the reaction. The term “stoicheion” in “Stoichiometry”, is an old Greek term for "element" whereas “metron” means "measure".
