Q: What is the most abundant element on Earth? A: Oxygen, which composes about 49.5% of the total mass of the Earth's crust, waters and atmosphere, according to the textbook βModern Chemistry.β Silicon is second at 28%.
The four elements comprising over 90% of living matter are C, H, N, and O.
Water would be the most abundant substance but if you're asking about elements then oxygen would make up the greatest percentage of body mass.
The valence of hydrogen which is a common element of living matter is 1. The other elements are oxygen which has a valence of 2, nitrogen has a valence of 3 and carbon has a valence of 4.
Oxygen (O)Carbon (C)Hydrogen (H)Nitrogen (N)These four elements make up 96% of living matter.
