Always in Motion Row one has a shell that can hold two electrons. That’s covered by 1s2. Row two of the periodic table corresponds to shell two, which can hold eight electrons. You can see those eight in 2s2 and 2p6. Finally, we have shell/row three. Since suborbitals can only hold so many electrons, you see them divided into s and p. Silicon only has four electrons in the third shell. Suborbital s can hold two, and the other two are found in p.

Silicon Silicon is the eighth most common element in the universe by mass, but very rarely occurs as the pure free element in nature. It is most widely distributed in dusts, sands, planetoids, and planets as various forms of silicon dioxide (silica) or silicates.easured by mass, silicon makes up 27.7% of the Earth's crust and is the second most abundant element in the crust, with only oxygen having a greater abundance. Silicon is usually found in the form of complex silicate minerals, and less often as silicon dioxide (silica, a major component of common sand).

Facts About Silicon Silicon is the seventh-most abundant element in the universe and the second-most abundant element on the planet, after oxygen, according to the Royal Society of Chemistry.About 25 percent of the Earth's crust is silicon; weirder spots where this element appears include menstrual cups, breast implants and oven mitts.iew full size image. Silicon is neither metal nor non-metal; it's a metalloid, an element that falls somewhere between the two. The category of metalloid is something of a gray area, with no firm definition of what fits the bill, but metalloids generally have properties of both metals and non-metals.
