PERIODIC TABLE
PERIODIC TABLE

Charles Janet developed the periodic table in 1928.
How the periodic table is organized:
Charles Janet’s periodic table was organized according all elements that had been discovering before 1928 according to the orbital filling. It also structures the electrons in ascending atomic order Describe the information the periodic table contains:

DISADVANTAGE:
* The periodic table has a rough tarnation from metal to none-metal. DISADVANTAGE:
* The periodic table has a rough tarnation from metal to none-metal. ADVANTAGES:
* Janet’s periodic table was helpful for writing electrons configurations.

* The periodic table was easier to read.
* It sectioned off none metal and metal
ADVANTAGES:
* Janet’s periodic table was helpful for writing electrons configurations. * The periodic table was easier to read.
* It sectioned off none metal and metal
The periodic table contains all 63 elements that were discovered before 1928 and contains the number in which they are ordered in.

Dmitri Mendeleev
Dmitri Mendeleev

Dmitri developed this periodic table in 1869.
How was the periodic table organised?
The periodic table is organised by rows of horizontal row of elements in the periodic table.

It is also organised by none metal and metal and was arranged in order of atomic mass
What does Dmitri’s periodic table contain?
Dmitri’s periodic table contained 58 elements and also contained 4 elements that had not been discovered yet and it contained the atomic mass of the elements.
DISADVANTAGES:
* When Dmitri put the elements in order of atomic mass, he had trouble getting iodine because iodine was similar properties to chlorine and bromine. But iodine had a low atomic mass. So iodine could not be in his rows. This caused Dmitri to break his own rule; he made for the periodic table. DISADVANTAGES:

MODERN PERODIC TABLE
MODERN PERODIC TABLE

Describe the modern periodic table?
The periodic table is made up of 109 elements. Most of the elements were discovered by Dmitri. Most of the periodic table now is based on Dmitri’s work on his periodic table and also Dmitri organized the elements into groups and periods. After Dmitri had trouble in his periodic table and died before he could finish, Herney Mosley solved the problem by changing Dmitri’s rule ( by using atomic mass to organize the table), and changed it to organize the periodic table into Atomic numbers.

The Structure of the Modern Periodic Table:
The modern periodic table was structures by horizontal rows (periods) by ascending order of atomic number and vertical columns (groups/families) based on similar physical characteristics. This then equalled to the amount of proton in the atomic nuclease of every element. They were also organised into types of metal

Information the periodic table contains:
The periodic table contains 109 elements. It contains what type of metal the elements are. The actinide and lanthanide series.
