Period 6 element years and is used in medical applications, industrial gauges, and hydrology. Although the element is only mildly toxic, it is a hazardous material as a metal and its radioisotopes present a high health risk in case of radioactivity releases. Barium is a chemical element with the symbol Ba and atomic number 56. It is the fifth element in Group 2, a soft silvery metallic alkaline earth metal. Barium is never found in nature in its pure form due to its reactivity with air. Its oxide is historically known as baryta but it reacts with water and carbon dioxide and is
Transuranium element found. Transuranium elements may be utilized to synthesize other super-heavy elements. Elements of the island of stability have potential important military applications, including the development of compact nuclear weapons. The potential every-day applications are vast; the element americium is utilized in devices like smoke detectors and spectrometers. Transuranium element The transuranium elements (also known as transuranic elements) are the chemical elements with atomic numbers greater than 92, which is the atomic number of uranium. All of these elements are unstable and decay radioactively into other elements. Of the elements with atomic numbers 1 to 92, most can be found in
