In chemistry an element is a species of atom having the same number of protons in its atomic nuclei that is, the same atomic number , or Z. In total, elements have been identified. The first 94 occur naturally on Earth , and the remaining 24 are synthetic elements. There are 80 elements that have at least one stable isotope and 38 that have exclusively radionuclides , which decay over time into other elements.

The individual Elements which are classified within each Group are individually listed below in the following table for your convenience. Elements classified as Metalloids have properties of both metals and non-metals. Some are semi-conductors and can carry an electrical charge making them useful in calculators and computers The Metalloids are: Boron Silicon Germanium Arsenic Antimony Tellurium Polonium Elements classified as Alkali Metals The 6 elements classified as " Alkali Metals " are located in Group 1 elements of the Periodic Table. Elements classified as Alkali Metals are very reactive metals that do not occur freely in nature. Alkali metals are soft, malleable, ductile, and are good conductors of heat and electricity. Instead, they are widely distributed in rock structures. Elements classified as Transition Metals are ductile, malleable, and conduct electricity and heat.

Parkside was nothing more than an innocent battleground for disreputable elements of our society, at war with one another. The world is developing a shared popular culture with elements drawn from around the globe.

Nitrogen is the chemical element with the symbol N and atomic number 7. It was first discovered and isolated by Scottish physician Daniel Rutherford in Although Carl Wilhelm Scheele and Henry Cavendish had independently done so at about the same time, Rutherford is generally accorded the credit because his work was published first. Nitrogen is the lightest member of group 15 of the periodic table, often called the pnictogens. It is a common element in the universe , estimated at about seventh in total abundance in the Milky Way and the Solar System. At standard temperature and pressure , two atoms of the element bind to form dinitrogen , a colourless and odorless diatomic gas with the formula N 2. Nitrogen occurs in all organisms, primarily in amino acids and thus proteins , in the nucleic acids DNA and RNA and in the energy transfer molecule adenosine triphosphate.
