Cadmium ( ) is a chemical element with the symbol Cd and atomic number 48.

Cadmium has 8 known meta states, with the most stable being < sup > 113m </ sup > Cd ( t < sub > ½ </ sub >

# Cadmium ( Cd )

* Cadmium, using willow ( Salix viminalis ): In 1999, one research experiment performed by Maria Greger and Tommy Landberg suggested willow has a significant potential as a phytoextractor of Cadmium ( Cd ), Zinc ( Zn ), and Copper ( Cu ), as willow has some specific characteristics like high transport capacity of heavy metals from root to shoot and huge amount of biomass production ; can be used also for production of bio energy in the biomass energy power plant.

Cadmium pigments are a class of pigments that have cadmium as one of the chemical components.

The abbreviation Ni-Cd is derived from the chemical symbols of nickel ( Ni ) and cadmium ( Cd ): the abbreviation NiCad is a registered trademark of SAFT Corporation, although this brand name is commonly used to describe all Ni – Cd batteries.

However, since the alkaline battery's chemical reaction is not reversible, a reusable Ni – Cd battery has a significantly longer total lifetime.

These ponds are contaminated with a variety of biological and chemical pollutants including polycyclic aromatic hydrocarbons ( PAHs ), heavy metals ( e. g. Hg, Cd, Zn, Ni ), and organic chemicals ( phthalates, etc .).

This element also has 8 known meta states with the most stable being < sup > 113m </ sup > Cd ( t < sub > ½ </ sub > 14. 1 years ), < sup > 115m </ sup > Cd ( t < sub > ½ </ sub > 44. 6 days ) and < sup > 117m </ sup > Cd ( t < sub > ½ </ sub > 3. 36 hours ).

The primary decay product before < sup > 112 </ sup > Cd is element 47 ( silver ) and the primary product after is element 49 ( indium ).

The atomic number uniquely identifies a chemical element.

Each element has a specific set of chemical properties as a consequence of the number of electrons present in the neutral atom, which is Z ( the atomic number ).

Hence it is the atomic number alone that determines the chemical properties of an element ; and it is for this reason that an element can be defined as consisting of any mixture of atoms with a given atomic number.

Argon ( ) is a chemical element with symbol Ar and atomic number 18.

The name " argon " is derived from the Greek word αργον meaning " lazy " or " the inactive one ", a reference to the fact that the element undergoes almost no chemical reactions.

Arsenic ( ) is a chemical element with symbol As and atomic number 33.

Antimony ( or ; ) is a toxic chemical element with symbol Sb and atomic number 51.

Actinium ( ) is a radioactive chemical element with symbol Ac and atomic number 89, which was discovered in 1899.

Americium ( ) is a transuranic radioactive chemical element that has the symbol Am and atomic number 95.

Astatine ( or ) is a radioactive chemical element with the chemical symbol At and atomic number 85.

An atom is classified according to the number of protons and neutrons in its nucleus: the number of protons determines the chemical element, and the number of neutrons determines the isotope of the element.

The electrons determine the chemical properties of an element, and strongly influence an atom's magnetic properties.

He proposed that each element consists of atoms of a single, unique type, and that these atoms can join together to form chemical compounds.

of atoms, in the modern sense of the basic unit of a chemical element.

* 1982 – The synthetic chemical element Meitnerium, atomic number 109, is first synthesized at the Gesellschaft für Schwerionenforschung in Darmstadt, Germany.

This text clarified the concept of an element as a substance that could not be broken down by any known method of chemical analysis, and presented Lavoisier's theory of the formation of chemical compounds from elements.

Allotropes are different structural forms of the same element and can exhibit quite different physical properties and chemical behaviours.
