and is used in the production of a wide variety of industrially important compounds. Sodium ions are essential to numerous biological processes in animals. Atomic number 11; atomic weight 22.9898; melting point 97.80°C; boiling point 883°C; specific gravity 0.971 (20°C); valence 1. SeePerio...
[soda+-ium(1)] SYMB:NaAn inorganic metallic element, atomic weight (mass) 22.98987, atomic number 11, specific gravity 0.971. Sodium constitutes about 0.15% of body mass. It is the most abundant cation in extracellular fluids, the main contributor to osmotic pressure and hydration, participates...
It provides atomic mass, mass excess, nuclear binding energy, nucleon separation energies, Q-values, and nucleon residual interaction parameters for atomic nuclei of the isotope Na-17 (Sodium, atomic number Z = 11, mass number A = 17). Landolt-Brnstein Homepage Introduction Index...

be easily cut with a knife. It is a good conductor of electricity and heat. Due to having low atomic mass and large atomic radius, sodium is third-least dense of all elemental metals and is one of only three metals that can float on water, the other two being lithium and potassium.[...
Natural sodium is the stableisotopeof mass 23. Of the radioactive artificial isotopes,sodium-22 (2.6-yearhalf-life, the longest half-life of a sodium isotope) is used as a radioactive tracer for natural sodium.Sodium-24(15-hour half-life) is limited in use by its short life and is pro...
and is treacherous when larger amounts of sodium are used. Larger pieces of sodium melt under the heat of the reaction, and the molten ball of metal is buoyed up by hydrogen and may appear to be stably reacting with water, until splashing covers more of the reaction mass, causing thermal...
What is the relative atomic mass of sodium? Sodium: On the periodic table of elements, the chemical element sodium is shown by the symbol Na. Sodium has an atomic number of 11, which means it has 11 protons. Key Terms Element: An element is a chemical substance that cannot be broken do...
