The name of the element with electron configuration 1s22s22p63s23p2 is silicon. The second most abundant element in the Earth's crust, silicon is a metalloid, an element that is neither metal nor nonmetal.Continue Reading
According to Chem Wiki from the University of California, Davis, silicon has four valence electrons, meaning it has four electrons in its outermost energy level. These four electrons play an important role in the chemistry of silicon. Silicon can use these electrons to chemically bond with other elements. These electrons are usually shared with other atoms.
Silicon lies in the carbon family of elements. Although silicon is not a very reactive element, it is usually not found in its free form in nature. The element reacts readily with oxygen to form silicon dioxide, or plain sand, and silicate minerals.Learn more about Atoms & Molecules
