When did Niels Bohr come up with his Bohr model?
The Bohr model was made around 1913. There isn't an exact date, it's unknown.
Did Dalton or bohr come first?
John Dalton came first; he proposed his atomic theory in the early 1800s, specifically around 1803. Niels Bohr, on the other hand, developed his model of the atom in 1913, which introduced the idea of quantized energy levels for electrons. Thus, Dalton's work predates Bohr's by over a century.
How Did scientist come to think that Niels Bohr's model was correct?
Introduced by Niels Bohr in 1913, the model's key success lay in explaining the Rydberg formula for the spectral emission lines of atomic hydrogen.The Bohr model is a primitive model of the hydrogen atom. As a theory, it can be derived as a first-order approximation of the hydrogen atom using the broader and much more accurate quantum mechanics, and thus may be considered to be an obsolete scientific theory. However, because of its simplicity, and its correct results for selected systems , the Bohr model is still commonly taught to introduce students to quantum mechanics, before moving on to the more accurate but more complex valence shell atom.
Did niels Bohr come up with anything?
Niels Bohr (1885-1962) studied and adapted the works of Heisenberg, Planck, and others who investigated the particle and wave concepts of matter and energy. He was one of the earliest to work on quantum mechanics, which addressed the particle concept of energy. He disagreed with Einstein over the concept of the photon. Bohr developed the simplest concept of electron orbitals, where negatively-charged electrons circle a positively charged nucleus. His 1913 model defined energy states and the concept of electron energy levels (now defined by the quantum theory, electron clouds, and valence shells). He won the 1922 Nobel Prize in Physics.
Who founded the atom?
Mr. John Dalton B..1766 D..1844 1803 john put it together. teacher and scientist about 4 yrs later Dalton wrote a book called " A New System of Chemical Philosophy. Me personaly hae never seen or read his book, but it is said to be the first book to use symbols to identify elements. The name Dalton was also used in the weight of atomic units Example hearing someone say its 230 daltons.

Where did bohrium's name come from?
The name of the chemical element bohrium is derived from the name of the Jewish physicist Niels Bohr.
What is the atom model called?
The atom model is called the "Bohr model," named after Niels Bohr who proposed it in 1913. This model describes the atom as a small, positively charged nucleus surrounded by negatively charged electrons in specific energy levels or orbits.

When did Dalton come up with the atom?
Dalton didn't discover the atom. Democritus did. Dalton, however was the first to use the word atom. which comes from the GGreek word atomos, meaning "cannot be split"
How did bohr and schrodinger describe the atom?
1-Electrons are assumed to revolve around the atomic nucleus in discrete orbitals,and the position of any particular electron is more or less well defined in terms of its orbitals 2-energies of electrons are quantized;that is, electrons are permitted to have only specific values of energies.
Who drew the first picture of an atom?
Several people have proposed different models for the appearance of an atom. One of the earliest of these was by John Dalton - who simply drew an atom as a solid sphere. The Bohr model is probably the most well-known, this contains orbits with electrons circling a central nucleus. Schrodinger's electron cloud model is the most recent that I know of.
Did the periodic table come before the atomic model?
The periodic table came after the atomic model. The modern periodic table was developed based on the atomic structure proposed by scientists such as John Dalton, J.J. Thomson, Ernest Rutherford, and Niels Bohr. Mendeleev's periodic table was published in 1869, while the atomic model continued to evolve throughout the late 19th and early 20th centuries.
