Did Bohr improved upon Dalton's atomic theory?
Yes, Bohr's atomic theory built upon Dalton's atomic theory by introducing the concept of energy levels and electrons moving in specific orbits around the nucleus. He also added the idea of quantized electronic transitions, which helped explain the spectral lines observed in atomic spectra.
What were Niels Bohrs contribution to atomic structure?
He understood the importance of quantum theory (and used it to explain the electromagnetic radiation produced when elements are excited when heated to high tempeatures or by being placed in discharge tubes).
What major contribution did john Dalton made to the atomic theory?
Dalton's Atomic Theory 1) All matter is made of atoms. Atoms are indivisible and indestructible. 2) All atoms of a given element are identical in mass and properties 3) Compounds are formed by a combination of two or more different kinds of atoms. 4) A chemical reaction is a rearrangement of atoms.
What are three things that wegener used to develop his theory of continental drift?
Wegener used evidence from fossils, rock formations, and the fit of the continents as key components to develop his theory of continental drift. By studying these factors, he proposed the idea that all continents were once part of a single supercontinent called Pangaea.
The atomic theory proposed by Dalton has been?
The atomic theory proposed by Dalton has been widely accepted and forms the foundation of modern chemistry. It states that all matter is composed of small, indivisible particles called atoms, which combine in simple whole number ratios to form compounds. Dalton's theory also introduced the idea that atoms of different elements have different properties.
What does symbol n refers in the Bohr theory of atomic structure?
There is no N in Bohrs. But his first name was Neils
What did leucippus contribute to the atomic model or theory?
he did not develop anything regarding the 'atomic theory' for he was against that theory.
How was bohrs atomic model similar to Rutherford's model?
atoms
What instrumental did Thomson use to develop his theory?
Thomson Atomic Model
What is Bohr atomic model name?
Neil Bohrs atomic model is simply called Bohrs model. It states that electrons have a certain amount of energy, so they must follow certain orbits. This is different from the modern atomic model.
What does bohrs model of the atom look like?
The Bohr atomic model is similar to solar system.
What does Bohrs diagram represent?
it represents where the atoms, protons, Atomic Mass, atomic number, and electrons where they are located on the nucleus.
Did people accept bohrs belief?
For a while, but eventually a new atomic model came out that we still use today.
Which method did dalton use to develop his atomic theory?
He studied the way in which elements combined during chemical reactions.
What is the significance of Dalton's atomic theory in understanding the concept of atomic mass units (amu)?
Dalton's atomic theory laid the foundation for understanding the concept of atomic mass units (amu) by proposing that elements are made up of indivisible particles called atoms. This theory helped scientists develop a method to measure the relative masses of atoms, which led to the creation of the atomic mass unit as a standard unit of measurement for atomic masses.
Bohrs atomic theory?
Niels Bohr devised the Bohr model, which depicts the atom as a small, positively charged nucleus surrounded by electrons that travel in circular orbits around the nucleus, with electrostatic forces providing attraction.http://en.wikipedia.org/wiki/Bohr_model
What did roger bacon do for atomic theory?
Roger Bacon, a medieval philosopher and scientist, did not directly contribute to atomic theory as it was developed centuries after his time. However, his emphasis on experimental method and empirical observation laid the foundation for the scientific approach that would later lead to the development of atomic theory.
