The Periodic Table of the Elements (including Atomic Radius)HydrogenH. indicates the mass number of the longest-lived isotope. Electron Affinity. Periodicity of physical properties of the elements in PeriodAtomic radius. hydro, water, and genes, forming) Hydrogen was prepared many years before it was recognized as a distinct substance by Cavendish in Named by Lavoisier, hydrogen is the most abundant of all elements in the universe. The heavier elements Atomic properties that are critical to the behavior of elements are electron configuration, atomic size, ionization energy, electron affinity, and electronegativity. Abundance in the Universe Atomic Number Symbol Name Ground-state Configuration Ground-state Level Ionization Energy (eV) †Based uponC. The metric adopted is the average distance from the nucleus Atoms do not have specific outer boundary; their atomic size is based on atomic radius, which is one-half the internuclear distance of two bonded identical atoms.

The electron configuration (nl#: spdf notation) gives the distribution of electrons in principal energy levels and sublevels of an atom. Abundance in the Sun. Electronegativity. Alkali metals Alkaline earth metals. indicates the mass number of the longest Relative Atomic Mass For radioactive elements, the mass of the most stable isotope is given in brackets Atomic (proton) Number Boiling pointMelting point (˚C) Atomic The atomic radius is one-half the distance between the nuclei of two atoms (just like a radius is half the diameter of a circle). Because an atom does not have a discrete boundary, there are various non-equivalent definitions of atomic radius, such as Van der Abundance in Humans. The atomic radius of a chemical element is a measure of the size of its atom, usually, the distance from the center of the nucleus to the outermost isolated electron. Atomic radii can be obtained from quantum Abstract: Atomic and cationic radii have been calculated for the firstelements, together with selected anionic radii.
