In this work I suggest that early twentieth century theoretical physicists did not have enough facts or experimental data to formulate a consistent atomic model and as a result the concept of the atom needs revised. I conclude that the new atomic model presented is based only on first ...

While the number of protons remains the same in all atoms of an element, the number of neutrons can vary. Thus, atoms of the same element can have different mass numbers, and these are called isotopes. The weight of an electron is almost negligible. Thus, the atomic mass of an atom is...
An atomic number of an element is the number of protons in all the atoms of that element. Atomic numbers are always whole numbers greater than zero, such as 1,2,3... since an atom cannot have a fractional number of protons. What is the difference between an atomic number and a mass ...

with particular attention given to the formation of ionic and covalent bonds and thecorrelationof the latter with molecular shapes. The more-sophisticated quantum mechanical approaches to bond formation are then described, followed by a survey of a number of special cases that raise interesting problem...
