what is the most common element by mass formation of earth pls follow me.
Answers
Answer:
iron
Explanation:
The most common element on Earth in terms of total mass is iron, the largest element generated in the largest stars. Iron comprises around 35% of the elements on Earth in terms of mass.
Answer:
Elements are different kinds of atoms, and as of 2020, 118 of them had been identified, 92 of which occur in significant amounts in nature. While it's impossible to know for certain the precise composition of the deeper layers of Earth, four elements alone make up almost 90 percent of the Earth's uppermost portion, or crust; four more account for nine-tenths of the remainder.
Earth's crust is made up almost entirely of eight elements, four of them alone claiming almost nine-tenths of this layer's total weight: oxygen comes in at 46.6 percent by mass, followed by silicon at 27.7 percent, aluminum at 8.1 percent and iron at 5 percent.
The remaining crust elements are calcium, 3.6 percent; sodium, 2.8 percent, potassium, 2.6 percent, and magnesium, 2.1 percent.
Nearly 100 percent of the mass of Earth's core is composed of the two elements iron and nickel. Scientists have concluded this from the knowledge that the core must be 13 times as dense as water, leaving only some combination of molten iron and nickel as plausible candidates.
Explanation:
If asked to list the chemical elements that make up most of the Earth, you might be surprised by how hard it is to guess the right elements without knowing more than the average person does about all of that dirt, rock and metal underfoot. (You would also want to know if your quizzer was inquiring about the composition of the atmosphere above the Earth, also a common geoscience topic.)
