The periodic table’s arrangement also allows scientists to discern trends in element properties, including electronegativity, ionization energy, and atomic radius. Many scientists worked on the ...

The chemical characteristics of the elements can equally well be studied, for there are the acid- and base-forming elements on the chart, whose zones gradually infiltrate from strong basic to weak ...

Atomic weights of 10 elements on periodic table about to make an historic change Date: December 16, 2010 Source: University of Calgary Summary: For the first time in history, a change will be made ...

The new table will reflect the fact that boron atoms can have atomic weights ranging from 10.806 to 10.821, depending on where in the world the element originates.

As an exposition of the simple applications of the atomic theory to chemistry, this account leaves little to be desired in clearness and accuracy. Nothing, however, is said of the recent work ...
