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 ...

Atomic Number Orbital Energy Levels When an electron is at a specific energy level, it is more likely to be found in certain portions of that level than others. Orbitals are the name for these sections. Sublevels are made up of orbitals with the same energy. A maximum of two electrons ca...
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 ...
Atomic Number: 1 Group: Group 1 Classification: Nonmetal Block: s-block Electron Configuration: 1s1 Phase at STP: Gas Melting Point: 13.99 K (−259.16 °C, −434.49 °F) Boiling Point: 20.271 K (−252.879 °C, −423.182 °F) ...
The reason the atomic number determines the chemical properties of an element is that the number of protons also determines the number of electrons in an electrically neutral atom. This, in turn, defines the electron configuration of the atom and the nature of its outermost or valence shell. Th...
