Periodic Table
The atoms have been arranged in a table called the Periodic Table.
In this table the atoms have been arranged in vertical columns based on the similar
chemical properties due to their electron configuration
Group 0 (col 18): Inert gases.. (filled electron shell, stable electron configuration )
Group VIIA(col 17): Halogens.. (one electron short of stable structure )
Group VIA (col 16): Two electrons short of stable structure
Groups 1A and IIA (cols 1 & 2): Alkali and Alkaline earth metals ( One or two electron in excess of stable structure )
Groups IIIB to IIB (cols 3 to 12): Transition metals (partially filled d electron states, one or two electrons in next shell )
Groups IIIA ,IVA, VA (cols 13,14,15) : Intermediate characteristics by virtue of valence electron stucture
Most metal elements are electropositive (capable of donating a few valence electrons )
In each cell the atomic number is included above the chemical symbol

Table of Atomic Properties of Elements
Note: The relative atomic mass A.Mass is the number of is the mass compared with carbon -12.
This is not a simple unit value based on the number of neutrons and protons
because all naturally occurring elements are composed of isotopes e.g. chlorine
consists of 75% Cl-35 and 25% Cl-37 . Therefore the AW of Cl = 0.75*35+ 0.25*37 = 35.5. There are also extremely small variations due to
mass to energy conversion related to binding energy of the atomic nucleus. The values in brackets are estimates
