Gold is a bright, slightly reddish yellow, dense, soft, malleable, and ductile metal. This variation is typically small for solids and liquids but much greater for gases. As the most electronegative element, it is extremely reactive: almost all other elements, including some noble gases, form compounds with fluorine. For this purposes, a dimensionless quantity the Pauling scale, symbol χ, is the most commonly used.

It is convenient form of iodine in aqueous solution. An iodide ion is the ion I .    Metalloids The periodic table is a tabular display of the chemical elements organized on the basis of their atomic numbers, electron configurations, and chemical properties. By mass, aluminium makes up about 8% of the Earth’s crust; it is the third most abundant element after oxygen and silicon and the most abundant metal in the crust, though it is less common in the mantle below. This nuclide is also newly made by cosmic rays and as a byproduct of artificial nuclear fission, which it is used to monitor as a very long-lived environmental contaminant.  Links, Show Table With:

Neptunium metal is silvery and tarnishes when exposed to air. Both the boiling points of rhenium and tungsten exceed 5000 K at standard pressure. Praseodymium is a soft, silvery, malleable and ductile metal, valued for its magnetic, electrical, chemical, and optical properties. The elemental metal is rarely found in nature, but once isolated artificially, the formation of an oxide layer (passivation) stabilizes the free metal somewhat against further oxidation. [citation needed] Nonpolar solvents such as hexane and carbon tetrachloride provide a higher solubility. Lead is widely used as a gamma shield.

Krypton is a member of group 18 (noble gases) elements.

Iodine is an essential component of the human diet and in fact appears to be the heaviest required element in the diet.

It is the Pauli exclusion principle that requires the electrons in an atom to occupy different energy levels instead of them all condensing in the ground state. Gold is thought to have been produced in supernova nucleosynthesis, from the collision of neutron stars.

These elements, along with the chemically similar elements scandium and yttrium, are often collectively known as the rare earth elements. Major advantage of lead shield is in its compactness due to its higher density. The I2 molecules tend to interact via the weak van der Waals forces called the London dispersion forces, and this interaction is responsible for the higher melting point compared to more compact halogens, which are also diatomic.

The chemical symbol for Fluorine is F. Fluorine is the lightest halogen and exists as a highly toxic pale yellow diatomic gas at standard conditions.

   Number of Neutrons

Neon is a colorless, odorless, inert monatomic gas under standard conditions, with about two-thirds the density of air. ), and shape.

The forces of chemical bonding causes this repetition. Iodine atoms have 53 electrons and the shell structure is 2.8.18.18.7. The first two columns on the left side of the periodic table are where the s subshells are being occupied.  It is a synthetic element (first synthesised at Hasse in Germany) and radioactive. How long will the footprints on the moon last? Why don't libraries smell like bookstores? Instead, iodine-129 is an extinct radionuclide, and its presence in the early Solar System is inferred from the observation of an excess of its daughter xenon-129. The deep blue colour with starch solution is characteristic of the free element.
