We elaborate the uses of Radium and atomic properties with characteristics. Radium is a silvery-white metallic chemical element with atomic number 88. Its symbol is Ra and it belongs to the group of alkaline earth metals and its normal state in nature is solid. The radius is located at position 88 on the periodic table.
On this page you can discover the chemical properties of radium and information about radium and other elements of the periodic table such as barium, francium, actinium or hydrogen. You will also learn what radium is for and what its uses are through its properties associated with radium such as its atomic number or the usual state in which radium can be found.
You will be able to see qualities of radium such as its melting and boiling point, its magnetic properties or what its chemical symbol is. In addition, here you will find information about its atomic properties such as the distribution of electrons in radio atoms and other properties.
For some elements, part of this information is unknown. In these cases we show the properties attributed to them.
The alkaline earth metals, among which radium is found, have properties among which are being soft, colored and having a low density. Elements like radium have low ionization energy. All alkaline earth metals form ionic compounds with the exception of beryllium.
The state of radius in its natural form is solid (not magnetic). Radium is a silvery-white metallic chemical element and belongs to the group of alkaline earth metals. The atomic number for radius is 88. The chemical symbol for radius is Ra. The melting point of radius is 973 degrees Kelvin or 700.85 degrees Celsius or degrees Celsius. The boiling point of the radius is 2010 degrees Kelvin or 1737.85 degrees Celsius or degrees Celsius.
Atomic properties of Radium
The atomic mass of an element is determined by the total mass of neutrons and protons that can be found in a single atom belonging to this element. Regarding the position to find the radius within the periodic table of elements, the radius is in group 2 and period 7. The radius has an atomic mass of (2260254) u u.
The electron configuration of the radius is [Rn] 7s2. The electronic configuration of the elements determines the way in which the electrons are structured in the atoms of an element. The atomic radius or Bohr radius of the radius is 215 pm.
