Was Dalton th first person to suggest the idea of atoms?
It was not John Dalton who first suggested the idea of atoms. It was the Greek philosopher and mathematician Democritus who first suggested the existence of atoms.
What was one idea Dalton taught about atom?
All atoms of one type were identical in mass and properties. (Apex 2021)
Who proposed that all atoms cannot be divided or destroyed and that atoms of the same element are exactly the same?
Dalton. Dalton's atomic theory stated that atoms are indivisible and indestructible and unchangeable.
Who was the first scientist to question the idea that atom were uncutable?
The first scientist to question the idea that atoms were indivisible was John Dalton, an English chemist, in the early 19th century. Dalton proposed that atoms were not actually indivisible, as previously believed, but rather could be rearranged in chemical reactions.
Who had as part of his atomic theory the idea that compounds are formed by joining of atoms?
john Dalton
Who is credited for developing the idea that atoms must have negatively charged electrons?
John Dalton
What is the relationship between Democritus and Dalton's atomic theory?
Democritus, an ancient Greek philosopher, first proposed the idea of atoms as indivisible particles. Dalton's atomic theory, developed in the 19th century, expanded on this concept by introducing the idea of atoms combining in specific ratios to form compounds. Dalton's theory built upon and refined Democritus' original idea of atoms, laying the foundation for modern atomic theory.
Who is a scientist in 1803 that proposed the idea that everything is made up of atoms?
you are probably referring to dalton
Who proposed the idea that everything is made of atoms?
It was John Dalton in the early 1800s.
Dalton's idea that atoms cannot be divided into smaller parts was disproved by the discovery of what?
Dalton's idea that atoms are indivisible was disproven by the discovery of subatomic particles, such as electrons, protons, and neutrons. These particles were identified through experiments in the late 19th and early 20th centuries, revealing that atoms are, in fact, composed of smaller components. Additionally, the discovery of nuclear reactions demonstrated that atoms could be split, leading to the release of energy and further challenging Dalton's original postulate.
What ideas about the atom did Democritus and John Dalton share?
Democritus and John Dalton both believed that atoms were indivisible and made up all matter. They shared the idea that atoms were small, solid particles that could not be divided further.
Did Dalton know that atoms contain subatomic particles?
No, Dalton believed that atoms were indivisible.
