In 1869, a Russian scientist named Dmitri Mendeleev arranged the elements in a table according to their Atomic Mass, this was the first Periodic Table. However, a few elements didn't fit the pattern in Mendeleev's table, so a new table had to be made, and that table is today's periodic table which is arranged by atomic number, and not atomic mass.

Dmitri Mendeleev, a Russian chemist
Groups are arranged as columns in the periodic table; the contained elements have similar properties.
Mendeleev developed the periodic table of elements by arranging the elements in order of increasing atomic mass in 1869. He discovered that elements with similar properties occurred in a periodic pattern. He was able to predict the properties of elements that were missing at the time because of this pattern. In 1914, Moseley contributed to the periodic table by reorganizing the elements according to atomic number.
unpredictable and pattern contradict one and other. and they follow the periodic table if they are elements, ions will not
the periodic law :)
Mendeleev was the scientist who first devised the periodic table of the elements. The pattern he found was that elements have periodic, or repeating series of properties. If you write down the elements in a series according to increasing atomic number, there is a repeating pattern; first metals, then nonmetals, then noble gases, then back to metals. This pattern helps us to understand why elements have the particular chemical properties that they have. It is fundamental to the science of chemistry.
The repeating pattern of elements of their properties is called periodicity. Elements are arranged according to same chemical properties.
Periodic law,,,
Periodic law,,,
the periodic table.
Periodicity, or periodic law.
The answer to, ' when repeating chemical and physical properties of elements change periodically with the elements' atomic numbers it is called the?'Periodic law, is the answer. PERIODIC LAW !orPeriodicity of the chemical elements properties.
Groups of the Periodic Table of Elements.

periodic table!!!!!!!!!!!!!!!!!!!! teehee
