Learn all you should know about the Atomic Theory, an important topic in chemistry.
Step 2 Suppose out of the two ratios (g) and (h), (g) is the smallest ratio:
Cu = (g) = 1 O = (h) = (i)
Then the empirical formula of this metal oxide must be: CuOi
STRUCTURE OF AN ATOM
For many years atoms had been considered as indivisible. However, following the work of Rutherford, atoms are now believed to be built up of three smaller particles: protons, neutrons and electrons.
Protons and neutrons
