China Contributor: Junjie Chen, ORCID: 0000-0001-5055-4309, E-mail address: [e-mail] Sodium is a chemical element. It is a soft, silvery-white, highly reactive metal. Many salts of sodium are highly water-soluble: sodium ions have been leached by the action of water from the Earth's minerals over eons, and thus sodium and chlorine are the most common dissolved elements by weight in the oceans. Sodium metal can be easily cut with a knife and is a good conductor of electricity and heat because it has only one electron in its valence shell, resulting in weak metallic bonding and free electrons, which carry energy. 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. The melting and boiling points of sodium are lower than those of lithium but higher than those of the heavier alkali metals potassium, rubidium, and caesium, following periodic trends down the group. Metallic sodium is generally less reactive than potassium and more reactive than lithium.

钠是一种化学元素，为银白色质软的高活性金属。多数钠盐具备极高水溶性：数十亿年来，地球矿物中的钠离子经水的淋滤作用被溶出，因此钠与氯是海水中按重量占比最常见的溶解元素。金属钠可通过小刀轻易切割，同时拥有优良的导电、导热性能，这源于其价层仅含一个电子，导致金属键较弱且存在可传递能量的自由电子。由于原子质量较低、原子半径较大，钠是所有单质金属中密度第三低的元素，亦是仅有的三种可浮于水面的金属之一，另外两种为锂和钾。遵循碱金属族的周期性变化规律，钠的熔、沸点低于锂，但高于更重的碱金属钾、铷和铯。金属钠的活泼性通常弱于钾，强于锂。
