In this case, a chemical method can provide a perovskite compound. This perovskite compound is called an ‘organic-inorganic perovskite compound’, because it contains an organic component. A metal ion component usually involves tin or lead.4,5) This perovskite compound has the general formula [(RNH3)mMXn], in which modifiions of metal (M), halide (X) and organic groups (R) precisely control physical properties.

Mendeleev believed, incorrectly, that chemical properties were determined by atomic weight. Of course, this was perfectly reasonable when we consider scientific knowledge in 1869. In 1869 the electron itself had not been discovered - that didn''t happen for another 27 years.
