What is the main difference between Bohr's model of an atom and the atomic theory that is currently accepted?
The Bohr Model of the structure of an atom states that the centrifugal force that tends to throw the electron outwards is counterbalanced by the electrostatic attraction between the electrons and the protons in the nucleus, therefore inhibiting the natural tendancy to spiral inward. He showed the the emission spectroptomy of an atom with a model known as the emission spectrum, using lines to represent suborbitals.
The Emission Spectrum works well with Hydrogen because it only has one valence electron, however with any other element, it fails miserably.
There are three main problems with the Bohr Model:
1. Wave-Partical Duality; The Bohr Model assumes that electron behave as particles, but in reality, they exhibit both particle AND wave-like properties.
2.Heisenberg's Uncertainty Principal: The more you focus on finding position of an electron, the less accurate your definition of its velocity is, and vice versa.
3.Inter-electronic Repulsion; The Bohr model does not take into account the repulsion between electrons in multi-electron atoms. We know that if two electrons are within the same orbital, due to their natural negative charge, they will have a tendancy to repulse eachother.
Schrodinger took these flaws into account and then built a new theory stating the we dont know exactly where an electron is located, nor do we know whether it travels in a circular path, but we CAN estimate the region of space around the nucleus where there is a probability of finding an electron, an orbital.

What is the major difference between the Bohr model and the accepted atomic model?
Bohr assumed that electrons moved in fixed orbits.
What is the difference between atomic mass and atomic mass unit?
The atomic mass unit is used to express the measure of the atomic mass.
What is the difference in atomic mass of iodine and magnesium?
Iodine is 127 and Magnesium is 24 so the difference is 103 atomic mass units.
What is an element with 20 neutrons?
Calcium-40: The atomic number of calcium is 20 and the number of neutrons is always the difference between the atomic mass and the atomic number.
What is the difference between H2 and H1 isotopes?
They have different numbers of neutrons and therefore different atomic masses. Hydrogen-2, with 1 protons and 1 neutron has an atomic mass of 2. Hydrogen-1, with 1 proton and no neutrons has an atomic mass of 1. (By the way, the accepted way of writing these symbolically if you can't use subscripts is to put the number first, vis: 2H)

What are the difference between atomic fission to atomic nuclear?
The difference between atomic fission and atomic nuclear is that they both have something to do with atomic and war. Hope this helps I am kind of in a rush......Smile!

What is the currently accepted atomic model?
The currently accepted atomic model is the quantum mechanical model, which describes the electron's behavior in an atom using probability distributions called orbitals. In this model, electrons do not follow fixed paths around the nucleus but are found in specific regions of space defined by these orbitals.
