aThe charge of an electron or of a proton is much too small to be basic quantity of charge of charge for almost all practical applications. The SI unit of charge is the coulomb, with the symbol C. A coulomb of negative charge equals that of 6.242(1018 electrons. The coulomb is a deriv...

aOne of the most fundamental concepts in electric circuit analysis is that of charge conservation.We know from basic physics that there are two types of charge:positive (corresponding to a proton),and negative (corresponding to electron).For the most part,this test is concerned with circuits in...
However, a second series (Q-series) of molecular ions is also apparent at m/z 837.6 (Q1), m/z 851.6 (Q2) and m/z 865.6 (Q3) that also differ in mass by a —CH2— unit and, in addition, are 16 Da smaller than the corresponding TUN components (Figure 2a). Reversed-phase HPLC ...
Each chemical element in the periodic table can be represented by a single atom, which has some numbers of sub-atomic proton, neutron and electron particles. The simplest atom will be the protium hydrogen isotope, which has 1 proton and 1 electron....
The ionization energy for a first shell electron in sulphur is 239 MJ. Predict whether you would expect the ionization energy for a first shell electron in phosphorus to be larger or smaller than this.Of the following elements, which is mo...
What is the difference between a light wave and a microwave? An electron has a speed of 0.75c. Find the speed of a proton that has (a) the same kinetic energy as the electron and (b) the same momentum as the electron. What elements ...
