5 most abundant elements
Visualizing the Abundance of Elements in the Earth''s Crust
The Earth''s crust comprises about 95% igneous and metamorphic rocks, 4% shale, 0.75% sandstone, and 0.25% limestone. Oxygen, silicon, aluminum, and iron account for 88.1% of the mass of the Earth''s crust, while another 90 elements make up the remaining 11.9%. While gold, silver, copper and other base and precious metals are …

What Is the Sun Made Of? Table of Element Composition
About 67 chemical elements have been detected in the sun. I''m sure you''re not surprised that hydrogen is the most abundant element, accounting for over 90% of the atoms and over 70% of solar mass. The next most abundant element is helium, which accounts for almost just under 9% of the atoms and about 27% of the mass.
Elements in the Human Body and What They Do
There are several ways to consider the composition of the human body, including the elements, type of molecule, or type of cells.Most of the human body is made up of water, H 2 O, with bone cells being comprised of 31% water and the lungs 83%. Therefore, it isn''t surprising that most of a human body''s mass is oxygen. Carbon, the …
15.1: The Structure and Composition of the Sun
About 73% of the Sun''s mass is hydrogen, and another 25% is helium. All the other chemical elements (including those we know and love in our own bodies, such as carbon, oxygen, and nitrogen) make up only 2% of our star. The 10 most abundant gases in the Sun''s visible surface layer are listed in Table 15.1.2 15.1. 2.
