What is Bohr and Chadwick atomic theory?
Bohr's atomic theory states that electrons orbit the nucleus in specific energy levels, or shells. Chadwick's theory proposed the existence of neutrons in the nucleus, along with protons, to account for the atomic mass of elements. Both theories were instrumental in shaping our understanding of the structure of atoms.
Whose Atomic theory states that atoms are featureless and solid?
That was the earliest version of atomic theory, proposed by the Greek philosopher Democritus.Democritus
What states that all matter is made up of particles?
The atomic theory states that all matter is made up of particles called atoms. These atoms combine to form molecules and substances.
Was Marie Curie a contributor to the atomic theory?
Marie Curie was not a direct contributor to the atomic theory, but her work in discovering the elements radium and polonium, as well as her research on radioactivity, helped further the understanding of atomic structure and the behavior of atoms. Her discoveries ultimately had a significant impact on the development of atomic theory.
Who revived the atomic theory and put on a solid experimental foundation in about 1803 by?
John Dalton revived the atomic theory in 1803 by proposing that elements were made up of tiny, indivisible particles called atoms. He also outlined basic principles of atomic theory and provided experimental evidence to support his ideas.

Both theories were instrumental in shaping our understanding of the structure of atoms.
How did subatomic particles and isotopes affect the atomic theory?
The discovery of subatomic particles like electrons, protons, and neutrons contributed to a better understanding of the structure of atoms. Isotopes, which are atoms of the same element with different numbers of neutrons, helped refine the atomic theory by explaining variations in atomic mass. Together, these discoveries have shaped our modern understanding of atomic structure and behavior.
What was the atomic theory about?
the structure of the atom
What was Moseley's atomic theory?
Moseley was the first to clear and scientifically justify in 1913 the atomic number studying X-ray spectra of chemical elements. But Moseley hadn't a personal atomic theory, he was not the discoverer of the atomic theory.
How did Moseley discover the atomic theory?
Moseley was the first to clear and scientifically justify in 1913 the atomic number studying X-ray spectra of chemical elements. But Moseley hadn't a personal atomic theory, he was not the discoverer of the atomic theory.
What was Mosley's atomic theory?
The physical & chemical properties of the elements are periodic functions of their atomic numbers.
The atomic theory was supported by mendeleev when scientist did what?
The atomic theory was supported by Mendeleev when scientists discovered that elements displayed a periodic trend in their properties when arranged by increasing atomic weight. Mendeleev used this information to create the periodic table, organizing elements by their atomic weights and predicting the properties of missing elements.
Whose Atomic theory states that atoms are featureless and solid?
That was the earliest version of atomic theory, proposed by the Greek philosopher Democritus.Democritus
Which scientist proposed that elements consisted of atoms were identical and had the same mass and that compounds were atoms from different elements combined together?
John Dalton first proposed this. Today, it's called Dalton's atomic theory.
When was Mendeleev's contribution to the atomic theory published?
Mendeleev's contribution to the atomic theory was published in 1869 in his book "Principles of Chemistry." In this work, he introduced the periodic table of elements, organizing them by atomic weight and properties, and leaving gaps for undiscovered elements.
What was hery Moseley's atomic theory?
Moseley was the first to clear and scientifically justify in 1913 the atomic number studying X-ray spectra of chemical elements. But Moseley hadn't a personal atomic theory.
Did daltons atomic theory include the idea that all atoms of all elements are the same size?
No, Dalton's atomic theory did not include the idea that all atoms of all elements are the same size. Instead, he proposed that atoms of different elements have different sizes and weights.
