The standard example is etching of silicon by alternating reaction with chlorine (Cl2) and etching with argon ions (Ar). In the first step, shown in figure 20, firstly, Cl2 reactants are adsorbed onto the Si film surface; and then excess reactants are purged; following with Ar ions ...
number and atomic number E.g.1 Oxygen: O 16 8 E.g.2 Oxygen - 16 E.g.3 O-16 These values are given on the periodic table. For now, round the mass # to a whole number. These numbers tell you a lot about atoms. # of protons = # of electrons = atomic number # of neutrons ...
