positive 'pudding' held the negative electrons
Atomic spectrum is a spectrum of radiation caused by electron transitions of energy levels within an atom. This is determined by E=h*f
The elements in the modern periodic tables have been arranged on the basis of their atomic numbers.

Mendeleev's periodic table was based on the atomic masses of elements. However, this was not effective when isotopes were discovered. An isotope of an element is defined as the element having the same atomic number but varying mass numbers. So, mass numbers weren't constant and hence, a better characteristic was chosen -atomic number. Atomic number of any element was a characteristic of a particular element. Hence atomic numbers were taken as the basis of classification instead of atomic masses.

The Periodic Table is organized by atomic number, metals, nonmetals, metalloids, periods, groups, and stability.
The stability in the empire provides a sound basis for arts and science.
anything which can't be explained on the basis of facts and logics can be termed as unscientific
Photo electric emission cannot be explained using wave theroy of light. We need quantum theory.

Assume many buyers and many sellers of a standardized product
the two party system is rooted in the beginning of the nation itself therefore it contributes to a historical basis
It is the atomic theory of matter
