Which element is most abundant in the Earth’s crust
A
Oxygen
B
Silicon
C
Aluminium
D
Iron
Explanation: 

Detailed explanation-1: -Oxygen is by far the most abundant element in the Earth’s crust, making up 46% of mass-coming up just short of half of the total. Oxygen is a highly reactive element that combines with other elements, forming oxides.

Detailed explanation-2: -The most abundant element in the earth’s crust is oxygen (46. 1%). The chemical formula of oxygen (dioxygen) is O2. This formula is given so because oxygen usually combines with another oxygen by forming a covalent bond.

Detailed explanation-3: -Oxygen is the most abundant element in the Earth’s crust. Since oxygen is reactive elements and forms compounds with most of the other elements hence it is found in abundance.

Detailed explanation-4: -Look at the properties of Oxygen and Silicon-the two most abundant elements in the Earth’s crust-by clicking on their symbols on the Periodic Table.

Detailed explanation-5: -(B) Oxygen ( O 2 ) is the most abundant non-metal in the earth’s crust. It is also the most prevalent element in the crust of the world. It accounts for around 46 percent of the earth’s crust, with silicon accounting for 28 percent and aluminum accounting for 8.3 percent.
