The line spectra of atoms provides experimental evidence for?
The line spectra of atoms provide experimental evidence for the quantization of energy levels in atoms. This supports the idea that electrons can only exist in specific energy levels within an atom's electron shells. The specific wavelengths of light emitted or absorbed by atoms in their line spectra confirm the discrete nature of energy levels and the transitions between them.
Are atoms destructible?
Atoms are not destructible in the sense that they cannot be destroyed or eliminated. However, they can undergo nuclear reactions or nuclear decay processes where the atom may change into a different element.
What experimental evidence led to bohr to believe that electrons can posses only specific amounts of energy?
The observation of discrete emission spectra from elements provided the experimental evidence for Bohr's model. The only way to explain these spectra was through quantization of electron energy levels in atoms. This led Bohr to propose that electrons could only exist in specific orbits with quantized energy levels.
Which scientist offered proof that atoms exist?
The existence of atoms was proposed by the ancient Greek philosopher Democritus in the 5th century BCE. However, John Dalton provided experimental evidence for the existence of atoms in the early 19th century through his atomic theory, which explained chemical reactions in terms of the combination of atoms.
What experimental evidence led to the formulation of the law of multiple proportions?
The experimental evidence by John Dalton, who analyzed the ratios of elements combining to form different compounds, led to the formulation of the Law of Multiple Proportions. This law states that when elements form different compounds, the ratio of the masses of one element that combine with a fixed mass of the other element can be expressed in small whole numbers.

Are atoms destructible?
Atoms are not destructible in the sense that they cannot be destroyed or eliminated. However, they can undergo nuclear reactions or nuclear decay processes where the atom may change into a different element.
Who found atoms to be destructible and changeable?
FALSE ,, because atoms can be destroyed by nuclear fusion
Who didn't have experimental evidence to support his theory of atoms?
The Greek philosopher Democritus first put forward the idea of atoms as an intellectual theory.
What experimental evidence did Thomson have atoms of all elements contain electrons?
The deflection of cathodic rays was the source of inspiration for Thomson.
What experimental evidence did Thomson have for the atoms of all elements contain electrons?
The deflection of cathodic rays was the source of inspiration for Thomson.
What is the elements in chemistry?
Atoms of chemical elements are non destructible by chemical methods. Characteristic is the number of protons.
Proposed that matter was made of tiny indivisible particles He called these units atoms He did not have evidence to support his theory?
The proposed individual indivisible particles were atoms, and this idea laid the foundation for modern atomic theory. Although he lacked experimental evidence at the time, subsequent scientific discoveries have validated the existence of atoms as building blocks of matter.

What is the relationship of atoms to matter?
An atom is the simplest unit of matter which is not destructible by chemical methods.
What was the first said by scientists about atoms?
Early scientists speculated that the concept of atoms could explain the behavior of matter. The idea of atoms was proposed by ancient Greek philosophers such as Democritus around 400 BC, suggesting that matter is composed of indivisible particles. It wasn't until modern times that scientists were able to provide experimental evidence for the existence of atoms.
