9.17.00 1:37 PM3 3.3 Periodic Table
Dmitri Mendeleev (1869)(1869)In 1869 Mendeleev and Lothar Meyer In 1869 Mendeleev and Lothar Meyer (Germany) published nearly identical (Germany) published nearly identical classification schemes for elements known classification schemes for elements known to date. The periodic table is base on the to date. The periodic table is base on the similarity of properties and reactivities similarity of properties and reactivities exhibited by certain elements. Later, Henri exhibited by certain elements. Later, Henri Moseley ( England,1887-1915) established Moseley ( England,1887-1915) established that each elements has a unique atomic that each elements has a unique atomic number, which is how the current periodic number, which is how the current periodic table is organized.table is organized.

The atomic radius of an element is a measure of the size of its atoms, usually the distance from the nucleus to the boundary of the surrounding cloud of electrons

Electron affinity is a measure of the energy that is released when an atom acquires an electron. We say that the more energy is released, the more readily the atom becomes an anion.
