is that it has been able to successfully explain nearly all experimental physics. particle physics is the study of the individual elements that comprise our universe. as most know, atoms are composed of smaller components; neutrons, electrons and protons. when electrons jump between atoms, new ...
In addition, his theory leads to a conclusion that protons and neutrons fill sub shells in a different way. This is because the protons are charged particles, and by Coulomb repulsion they try to get as far away from each other as possible, hence tending to occupy the outer regions of ...
It does not matter how many neutrons and electrons are present in an atom. The Z is always determined by the number of protons. For example, If an atom has one proton then the Z is 1 and the element is hydrogen. Every iodine atom has 53 protons and the Z of iodine is 53. ...
