Periodic Simple Average Price Method : This method is similar to Simple Average Price Method except that the average price is calculated at the end of the concerned period.
Periodic Simple Average Price Method : This method is similar to Simple Average Price Method except that the average price is calculated at the end of the concerned period.
This method is like weighted average price method, except that the calculations of issue prices are made periodically (say, a month).
When Mendeleef arranged the elements in order of increasing atomic masses, he observed that the elements with similar properties appeared at regular intervals. This led him to state his famous periodic law in 1869. The Mendeleef’s Periodic Law states that:
In 1913, H.G.J Moseley in England proved that the more fundamental properties of an element are its atomic number. Therefore he suggested that the basis of classification of elements should be atomic number. This led to the modern periodic law, which states that..
