After oxygen, which is the most common element on Earth?
On earth, oxygen is the most common element, making up about 47% of the earth’s mass. Silicon is second, making up 28%, followed by aluminum (8%), iron (5%), magnesium (2%), calcium (4%), sodium (3%), and potassium (3%). All of the remaining elements together make up less than 1% of the earth’s mass.
Im sorry to say but that would be silicon… Silicon is the second most common element on earth. It is in over 90% of the worlds crust. The reason it is the second most common element is because it likes to form a tetrahedra with oxygen. Tetrahedra like are even easier to bond forming chains double chain, and sheets.
