The modern periodic table is arranged in ascending order according to atomic number. An element's atomic number is equal to the number of protons in each atom. Within this order, e...
The Periodic Table of Elements
Dmitri Mendeleev generally is credited with the creation of the first periodic table, which charts the chemical elements by atomic number and valence shell electron configuration.
The periodic table is a tabular arrangement of the chemical elements, ordered .....
Modern quantum mechanical theories of atomic structure explain group trends ...
Later, Henry Gywn-Jeffreys Moseley showed that the atomic number of an
element is numerically equal to the number of electrons round the nucleus.
Mendeleev's periodic table
doesn't look a whole lot like the modern periodic table
, but it uses a similar format. The elements are grouped in order of increasing atomic weight (we use atomic number now) in a way where elements with common properties appear together, i... More »
