How is the chemical symbol determined
WebThe identity of an element is determined by the number of protons. One cannot alter the number of protons without altering the identity of the element. By adding a proton, the atomic number increases by one and the element identity changes. Number of neutrons can be altered to create isotopes. Number of electrons can be altered to create ions. WebSo A is the mass number, which is equal to the number of protons, that's the atomic number which we symbolized by Z, plus the number of neutrons. So A is equal to Z plus N. And for protium, let's look at protium here. So in the nucleus there's only one proton and zero neutrons, so one plus zero gives us a mass number of one.

WebThe symbol pH is used to denote the hydrogen ion concentration. Mathematically, pH is defined as the negative logarithm to the base 10 of the hydrogen ion concentration expressed in molarity, i.e. pH = – log [H + ]. This results in the following scale at 25 °C: pH > 7 – alkaline solution pH = 7 – neutral solution pH < 7 – acid solution
