Textbook Question

Chapter 15, Problem 1MC

The most abundant element in the earth’s crust is

a. oxygen
b. nitrogen
c. silicon
d. carbon

Expert Solution & Answer

To determine

The most abundant element in the Earth’s crust.

Answer to Problem 1MC

Option-(a)-“Oxygen”

Explanation of Solution

The outer part of the Earth is called the crust is almost composed of rock. Earth’s crust consists of a very few abundant elements. Most of the elements are present in minor amounts.

Conclusion:

Oxygen is the most abundant element of the Earth’s crust, which is of about 46.6% of the total mass of the Earth’s crust. Silicon stands at the second place, which has about 27.7% of mass; whereas calcium is 3.6%, sodium is 2.8%, potassium is 2.6%, and magnesium is 2.1%. All the other elements occupy the remaining portion. Hence, option (a) is correct.

As silicon, nitrogen, and carbon occupy a less percentage of mass than oxygen, options (b), (c), and (d) are incorrect.
