Over 97 percent of the matter in living things is made up of 4 elements?
The four elements that make up over 97% of the matter in living things are carbon, hydrogen, oxygen, and nitrogen. These elements are essential building blocks for biological molecules like carbohydrates, proteins, and nucleic acids, which are crucial for life processes.
Who taught that the world is not made of atoms but is made of 4 elements?
The ancient Greek philosopher Empedocles taught that the world is made up of four fundamental elements: earth, water, air, and fire. He proposed that these elements combine and separate through the forces of love and strife, forming all matter and phenomena in the universe. This concept was influential in classical philosophy and persisted until the rise of atomic theory.
How many different substances can be made with four elements?
It depends on the elements! If two of them are carbon and hydrogen, hundreds of compounds can be made from these elements alone. If the four elements are all noble gases, no new substances can be made from them by chemical reaction.
What the unverse is made of?
The universe is primarily made up of dark matter, dark energy, and normal matter. Normal matter includes atoms and particles like protons, neutrons, and electrons that make up stars, planets, and the things we see around us. Dark matter and dark energy are mysterious components that scientists are still trying to understand.
How many groups of elements are there in the modern periodic table?

This theory was later replaced by the modern understanding of elements as defined by the periodic table in chemistry.
