Bohr model of the atom is defined as the atom as a series of
energy levels called as principle quantum shells, which are
progressing at greater distance from the nucleus. When first shell
is hold up to two electrons, then it is full and electrons start to
fill the next shells.
When we know atomic number for an atom, then start by putting
electrons in to innermost shell which is n=1 shell, when this is
full, then next shell accept 8 electrons. At n=3 energy level that
can hold up to 18 electrons, but accepts it will only 8 ...
For neon,
We know that the atomic number is equal to number of electrons. And
there are 10 electrons in a neon atom. According to Bohr model, two
electron shells surrounding the nucleus, which has 2 electrons in
the n=1 shell and 8 electrons in the n=2 shell.
Electron configuration of a neutral neon atom: 1s2 2s2 2p6
Valence electrons: 8
Why did the scientists had to come up with a different model after Bohr? a) Bohr considered electrons to have both a known radius and orbit b) Bohr assumed that electrons emit/absorb a photon when changing orbitals c) All mentioned reasons d) Bohr could not predict the orbitals of electrons of larger atoms

The structure of an atom of hydrogen can be described by the Bohr Model as well as the Quantum Mechanical Model. How are these descriptions similar? How are these descriptions different?
in a hydrogen atom. 8. Using the Bohr model, determine the wavelength when an electron in n=1 is excited to n = 3. 9. How are the Bohr model and the quantum mechanical model of the hydrogen atom similar? How are they different? 10. What are the allowed values for each of the four quantum numbers: n, l, m, and m?
Identify the orbits in the Bohr Model of the Hydrogen atom responsible for each quantum state. The Bohr Model provides that the radius of the electron’s orbit is given by: r = 0.529 x n 2 [Angstroms] (Eq. 8) where n is the state’s quantum number. Calculate the radius of each of these orbits.
Bohr Atom 01 Due this Tuesday, Apr 24 at 11:45 am (EDT) The Bohr Model of the hydrogen atom proposed that there were very specific energy states that the electron could be in. These states were called stationary orbits or stationary states. Higher energy states were further from the nucleus. These orbits were thought to be essentially spherical shells in which the electrons orbited at a fixed radius or distance from the nucleus. The smallest orbit is represented by n=1,...
