Figure 1 shows the abundance of elements in Earth’s crust. Figure 1. The Elite Eight Elements. The elements are listed along the x-axis and the percentage is on the y-axis. All numbers are approximate. Oxygen is just below 50 percent; silicon is just about 25 percent. Calcium is 5 ...
Silicon: Second-Most Abundant Element in Earth’s Crust Silicon, Si, is a metalloid, the second most abundant element in the Earth's crust and accounts for28 percentof the crust's mass. Combined with oxygen, it forms silicate materials, such as silicon dioxide, SiO2. Sand consists mostly ...
