The element silicon is created through a process where carbon and sand are heated to temperatures close to 3,992 degrees Fahrenheit. Silicon is also very abundant in the Earth's crust and is the seventh most plentiful element in the universe. Silicon was first discovered by a Swedish chemist named Jons Jacob Berzelius in 1894.
The element silicon is a semi-metal solid at room temperature. It has a boiling point of 5,909 degrees Fahrenheit, a melting point of 2,577 degrees Fahrenheit and a density of 2.3296 grams per cubic centimeter. Silicon has an atomic weight of 28.855 and is assigned the atomic number 14, group number 15 and period number 3 on the period table of elements. Many useful compounds are formed by silicon and used to manufacture medical implants, transistors, microchips, lubricants, glass and many other products used by people in every day life.Learn More

Each sublevel has differing numbers of orbitals. Sublevels are designated with lower-case letters. Sublevel s contains one orbital, p contains three, d has five, f has seven, g has nine, h has 11 and i has 13.Full Answer >
The orbital notation or electron configuration for potassium is 1s2 2s2 2p6 3s2 3p6 4s1 or 2, 8, 8 and 1 electrons per shell. The atomic number of potassium is 19, and thus it has 19 electrons and 19 protons.Full Answer >
The element with 27 electrons in an orbital diagram is cobalt. Cobalt has 27 protons, so it has 27 electrons. The 22 different isotopes of cobalt each have a different number of neutrons, with atomic numbers ranging from 50 to 72.Full Answer >
