there is no such thing as the four elements that make up the world... this was believed in ancient times... these four elements were wind, fire, earth and water but now since we hav e developed and now have a greater undertanding of the world we live in we have discovered that there are alot of "real" elements that make up the world

The four elements that make up about 96% of body matter are oxygen, carbon, hydrogen, and nitrogen. These elements are essential for various biological processes in the human body, such as respiration, energy production, and building proteins and DNA.
Aristotle's model of matter includes four fundamental elements: earth, water, air, and fire. He believed that all matter is composed of these elements, each associated with specific qualities—earth is cold and dry, water is cold and wet, air is hot and wet, and fire is hot and dry. Additionally, Aristotle proposed that these elements could transform into one another through the process of change and the influence of two properties: hot/cold and wet/dry.
empodocles theory was that all matter consisted of four elements: earth, air, water, and fire.
Carbon, hydrogen, oxygen, and nitrogen are the four essential elements that make up most living matter. These elements are crucial for building biological molecules such as carbohydrates, lipids, proteins, and nucleic acids, which are essential for life processes.
The atomic symbols for the four elements that make up the bulk of all living matter are carbon (C), hydrogen (H), oxygen (O), and nitrogen (N). These elements are essential building blocks for molecules such as carbohydrates, proteins, lipids, and nucleic acids found in living organisms.

Aristotle believed that all matter was composed of the four elements: earth, air, fire, and water. He thought that these elements combined in different proportions to create everything in the physical world.
Aristotle thought matter was made up of combinations of four basic elements, earth, water, air and fire.
The four elements comprising over 90% of living matter are C, H, N, and O.
Yes, in ancient Greek philosophy, it was believed that all matter was composed of these four elements: air, earth, fire, and water. They thought that different proportions of these elements gave rise to the diversity of materials found in the world. This concept was known as the theory of the four elements.
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.
