Question

what is bohrs atomic model??​

Answer 1

Answer: The Bohr Model has an atom consisting of a small, positively-charged nucleus orbited by negatively-charged electrons.

The modern model of the atom is based on quantum mechanics. The Bohr Model contains some errors, but it is important because it describes most of the accepted features of atomic theory without all of the high-level math of the modern version.

Main Points of the Bohr Model

•    Electrons orbit the nucleus in orbits that have a set size and energy.

•    The energy of the orbit is related to its size. The lowest energy is found in the smallest orbit.

•    Radiation is absorbed or emitted when an electron moves from one orbit to another.

Problems with the Bohr Model

•    It violates the Heisenberg Uncertainty Principle because it considers electrons to have both a known radius and orbit.

•    The Bohr Model provides an incorrect value for the ground state orbital angular momentum.

•    It makes poor predictions regarding the spectra of larger atoms.

•    It does not predict the relative intensities of spectral lines.

•    The Bohr Model does not explain fine structure and hyperfine structure in spectral lines.

•    It does not explain the Zeeman Effect.

Answer 2

Answer:

Explanation:

The BOHR MODEL has an atomic consisting of a small positively charged nucleus orbited by negatively charged electron. here's a closer look at the bohr model which is sometimes called the RUTHERFORD BOHR MODEL.

niels bohr proposed the bohr model of the atom in 1915. the model number of atom is based on the quantum mechanics. the model contains some errors, but it is important because it describes most of the accepted features of atomic theory without all the levels of the modern vision. unlike earlier model bohr model explain the RYDBERG formula for the special emission lines of atomic hydrogen.

1. electrons Orbits the nucleus in Orbit that have a set size and energy.

2. the energy of the orbit is related to its size .the lowest energy is found in the smallest Orbit.

3. radiations is observed or emitted when an electron move from one Orbit to another.
