The superscript A
before the element (symbol) indicates the
element is antimatter.
Examples, AntiLanthanum is ALanthanum
(ALa) and
AntiCerium is ACerium
(ACe).
See Rosetta Stone for Matter &
Antimatter Definitions
Identification for each of the antimatter element includes the following nuclear,
physical and chemical properties:
- Nuclear: Number of Aprotons/positrons,
atomic number, atomic mass, group and period in the Periodic Table of Matter and AntiMatter Elements,
Element's Family, bonding radius in angstroms, atomic radius in angstroms, atomic
volume in centimeters/mole, number/range/atomic masses of Aisotopes and
stable Aisotopes.
- Physical: general description, density in grams/centimeter
cubed, melting point in degrees Celsius, boiling point in degrees Celsius,
specific heat in Joules/gram degree, heat of vaporization in Kilojoules/mole,
heat of fusion in kilojoules/mole, electrical conductivity in 106 /centimeter
ohm, and thermal conductivity
in watts/centimeter degrees.
- Chemical: valance number, positron configuration, positronpositivity, 1st, 2nd, and 3rd
ionization potentials in volts.
The Rare Earth (Lanthanide
Series) elements are in Group 3, Period 7 of the
Periodic Table of Matter-AntiMatter Elements.
