Which is the second most abundant element in the Earth’s crust?

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. Besides computer chips, silicon has many uses; weirder spots where this element appears include menstrual cups, breast implants and oven mitts — in the form of silicone.

Silicon is a main ingredient in very low-tech creations, including bricks and ceramics. But the high-tech stuff is where the element really makes its mark. As a semiconductor, silicon is used to make transistors, which amplify or switch electrical currents and are the backbone of electronics from radios to iPhones.
