List of Elements of the Periodic Table Sorted by Atomic

Atomic number: The number of protons in an atom. Each element is uniquely defined by its atomic number. Atomic mass: The mass of an atom is primarily determined by the number of protons and neutrons in its nucleus. Atomic mass is measured in Atomic Mass Units (amu) which are scaled relative to carbon, 12 C, that is taken as a standard element

Periodic table Wikipedia

The atomic number is the absolute definition of an element and gives a factual basis for the ordering of the periodic table. [76] With the development of modern quantum mechanical theories of electron configurations within atoms, it became apparent that each period (row) in the table corresponded to the filling of a quantum shell of electrons.

Sep 09, 2017· The periodic table of elements is an atomic organisation based on two axis. The horizontal axis establishes an increasing order based on the atomic number (number of protons) of each element. The vertical arrangement is managed by the electronic configuration and presents a taxonomic structure designed by the electrons of their latest layer .

The Periodic Table of Elements

The periodic table of the chemical elements is a tabular display of the known chemical elements. The elements are arranged by electron structure so that many chemical properties vary regularly across the table. Each element is listed by its atomic number and chemical symbol. The standard table provides the necessary basics.
