What is the contribution of Luther Meyer in chemistry?
Julius Lothar Meyer was a contemporary of Mendeleev and like him and Newlands made contributions to the classification of elements in what we now call the periodic tabel.
Why where the lanthanide and actinide elements droped out of order on the periodic tabel?
The vertical columns of the periodic table are arranged to contain elements that have similar chemical and physical properties.The two rows at the bottom (called the Lanthanide and Actinide series) are elements that would all fit into group IIIB, in periods (horizontal rows) 6 and 7. since there is only one spot on the chart for all the elements in each series, they are listed separately at the bottom of the table.

How did John Kepler know where to leave spaces in the periodic table for undiscovered elements?
Kepler was a mathematician, astronomer and astrologer. He did no work with the periodic tabel, which hadn't been discerned yet, at any rate - that was Mendeleev, some centuries later.
How has the periodic tabel chenged through the years?
Additional elements have been discovered and added including the synthetic elements. Some of the previously "synthetic" elements have been discovered to be naturally occurring, and have been changed to reflect this. The Atomic Mass calculations have been improved.
What elements are found in Halogens?
Halogens are the 17th group (column) on the periodic table. This is the most reactive non-metal group. The five halogens are:Fluorine (F)Chlorine (Cl)Bromine (Br)Iodine (I)Astatine (At)
