The first known contributor to atomic theory was the ancient Greek philosopher Democritus, who lived around 460-370 BCE. He proposed that all matter is composed of indivisible particles called "atomos," meaning "uncuttable." Although his ideas were largely philosophical and lacked empirical support, they laid the groundwork for later scientific developments in chemistry and physics. It wasn't until the 19th century that John Dalton formulated a more comprehensive atomic theory based on experimental evidence.
What else can I help you with?
What experiment did Antoine Lavoisier do for his atomic theory?
Lavoisier is not known for an atomic theory.
What was the date that Niels Bohr discovered atomic theory?
Niels Bohr's atomic theory, known as the Bohr model, was proposed in 1913. This theory revolutionized our understanding of atomic structure by introducing the concept of quantized energy levels within the atom.
What was Joseph lucas contribution to atomic theory?
Joseph Lucas is not primarily known for contributions to atomic theory; rather, he was an English inventor and industrialist associated with the automotive and electrical industries. The development of atomic theory is more commonly attributed to scientists such as John Dalton, J.J. Thomson, and Niels Bohr. If you meant another figure or are looking for information on a different aspect of atomic theory, please clarify!
Was eugen goldstein atomic theory correct and how?
Eugen Goldstein's atomic theory was not entirely correct. He proposed the existence of a positively charged particle known as the "proton," which was a significant contribution to the understanding of atomic structure. However, his theory also included the idea of "cathode rays" being composed of a new form of matter, which was later disproven.
Did john Dalton have a nickname?
He is color blind and he named color blindness of red, blue, purple, and yellow. he named it daltonisum.
What experiment did Antoine Lavoisier do for his atomic theory?
Lavoisier is not known for an atomic theory.
Who is the best known contributor in the development of evolutionary theory?
Charles Darwin
When did Democritus make his first discovery?
Democritus is known for his atomic theory, which he developed in the 5th century BC. His ideas were revolutionary for the time and laid the groundwork for modern atomic theory.
What is the first theory to relate chemical changes to events at the atomic level?
The first theory to relate chemical changes to events at the atomic level was proposed by John Dalton in the early 19th century. Known as Dalton's atomic theory, it stated that elements are composed of indivisible particles called atoms, and chemical reactions involve the rearrangement of these atoms to form new substances.
What element is named after a scientist who was known for his theory on relativity?
The element named after a scientist known for his theory of relativity is einsteinium, with the atomic number 99. It was discovered in the debris of the first hydrogen bomb test in 1952.
For what is John Dalton known?
i think he discover atomic theory.
What was the date that Niels Bohr discovered atomic theory?
Niels Bohr's atomic theory, known as the Bohr model, was proposed in 1913. This theory revolutionized our understanding of atomic structure by introducing the concept of quantized energy levels within the atom.
How is the modern atomic theory different from Daltons atomic theory?
In Dalton's theory the electrons in the atom travel in a one layered orbital rotation around the nucleus, in the modern, or electron cloud, theory the electrons travel in a more radical patterned movement while still staying in their respected energy levels.

Who is the scientist who made important contributions to atomic theory?
One scientist who made important contributions to atomic theory is John Dalton. He is known for his work on the atomic theory of matter, proposing that all matter is made up of tiny, indivisible particles called atoms. His ideas laid the foundation for modern chemistry.
