Robert Boyle proposed a definition of chemical elements that led to the currently accepted definition. His definition is strikingly similar to Aristotle's earlier definition. In The Sceptical Chymist (1661) Boyle wrote, "I now mean by elements … certain primitive and simple, or perfectly unmingled bodies; which not being made of any other bodies, or of one another, are the ingredients of which all those called perfectly mixed bodies [chemical compounds] are immediately compounded, and into which they are ultimately resolved." However he also declared that elements must be identified by experiments, not by "pure reason" as Aristotle had identified his four classical elements.
In 1789 Antoine Lavoisier published a list of chemical elements based on Boyle's definition.
In 1803 John Dalton proposed (as part of his atomic theory) that all atoms of an element have identical properties (including mass), that these atoms are unchanged by chemical action, and that atoms of different elements react with one another in simple proportions.
in 1869 Dmitri Mendeleev was the first to publish a Periodic Table of the then known elements similar to the one used today.
Many other scientists also made contributions to this idea over time.

Who proposed each element is composed of extremely small particles called atoms?
The concept of atoms was proposed by the Greek philosopher Democritus around 400 BCE. However, the modern atomic theory was developed by John Dalton in the early 19th century, which expanded on the idea of atoms as indivisible particles that make up all matter.
Who is The schoolteacher who studied atoms and proposed an atomic theory?
The schoolteacher who studied atoms and proposed an atomic theory was John Dalton, known for his development of modern atomic theory in the early 19th century. Dalton's theory proposed that all matter is composed of small, indivisible particles called atoms that are unique to each element and are rearranged in chemical reactions. His work formed the foundation for modern chemistry.
Who first used the term element?
The term "element" was first used by the ancient Greek philosopher Empedocles in the 5th century BCE. He proposed that all matter is composed of four fundamental elements: earth, water, air, and fire. This concept influenced later philosophers and scientists, including Aristotle, who expanded on the idea by adding a fifth element, aether. The modern understanding of elements, particularly in chemistry, evolved much later with the development of the periodic table.
Which scientist said that atoms are the smallest particle of an element that retains its chemical properties?
John Dalton, an English scientist, proposed the theory that atoms are the smallest particle of an element that retains its chemical properties. His work on atomic theory laid the foundation for modern chemistry.
What man proposed that cells are formed from other cells?
Rudolf Virchow proposed the concept that cells are formed from pre-existing cells in 1855. This idea challenged the prevailing notion of spontaneous generation and laid the foundation for the modern cell theory.
What was Aristotle's idea about what made up objects?
from Wikipedia :Aristotle proposed a fifth element, aether, in addition to the four proposed earlier by Empedocles.Earth, which is cold and dry; this corresponds to the modern idea of a solid.Water, which is cold and wet; this corresponds to the modern idea of a liquid.Air, which is hot and wet; this corresponds to the modern idea of a gas.Fire, which is hot and dry; this corresponds to the modern idea of heat.Aether, which is the divine substance that makes up the heavenly spheres and heavenly bodies (stars and planets).

Who stated modern definition of chemical element first?
The modern definition of a chemical element was first proposed by English chemist Robert Boyle in the 17th century. He defined an element as a substance that cannot be broken down into simpler substances by chemical means.
Who first proposed the idea of space exploration by rocket?
Konstantin Tsiolkovsky, a Russian scientist, first proposed the idea of using rockets for space exploration in the early 1900s. His work laid the foundation for modern astronautics.

What idea lyell present?
Charles Lyell presented the idea of uniformitarianism, which proposed that the Earth's geological processes operate at a constant rate over time. This idea was a key concept in shaping modern geology and understanding the Earth's history.

Who first proposed the modern idea of elements and compounds?
Antoine Lavoisier, a French chemist, is often credited with introducing the modern idea of elements and compounds in the late 18th century. He is known for his work on the law of conservation of mass and for developing a system of naming chemical substances.
