Sodium and potassium are closely interconnected but have opposite effects in the body. Both are essential nutrients that play key roles in maintaining physiological balance, and both have been linked to the risk of chronic diseases, especially cardiovascular disease.
Home Science Chemistry. Chemical properties. Generally, elemental sodium is more reactive than lithium, and it reacts with water to form a strong base, sodium hydroxide (NaOH). Its chemistry is well explored. Reaction with air, water, and hydrogen.
Sodium is an alkali metal, being in group 1 of the periodic table. Its only stable isotope is 23 Na. The free metal does not occur in nature and must be prepared from compounds. Sodium is the sixth most abundant element in the Earth's crust and exists in numerous minerals such as feldspars, sodalite, and halite (NaCl).
Sodium is the 11th element in the periodic table and has a symbol of Na and atomic number of 11. It has an atomic weight of 22.98977 and a mass number of 23. Sodium has eleven protons and twelve neutrons in its nucleus, and eleven electrons in three shells. It is located in group one, period three and block s of the periodic table.
Properties. Sodium is a light-weight, silver -colored metal. Sodium is soft. It can easily be cut with a knife. When someone cuts it, the exposed part will become white over time. It reacts with air to form sodium hydroxide and sodium carbonate. Sodium is a little less dense than water.
