硫的奥秘！地球生命诞生的必要元素！The Mystery of Sulfur!

硫是一种非金属元素，化学符号为S，原子序数为16。它是地球上最早形成的元素之一，它主要来源于太阳系的原始星云，也可能来自于超新星爆发。它在地球的地壳、地幔、大气和海洋中都有分布，其中以地壳中的硫化物和硫酸盐矿物最为丰富。 Sulfur is a non-metallic element with the chemical symbol S and atomic number 16. It is one of the earliest elements formed on Earth, mainly originating from the primordial solar nebula and possibly also from supernova explosions. It is distributed in the Earth's crust, mantle, atmosphere, and oceans, with sulfide and sulfate minerals being most abundant in the crust. 硫有多种化合价和形态，常见的有-2, 0, +4, +6等，可以以单质、硫化物或硫酸盐的形式存在于自然界中。硫的单质形态有两种，一种是黄色的晶体，另一种是红色的液体。硫的硫化物形态有很多，如硫化氢、硫化铁、硫化铜等，它们的颜色和性质各不相同。硫的硫酸盐形态也有很多，如硫酸、硫酸铵、硫酸钙等，它们是许多工业和农业产品的原料或副产品。 Sulfur can have multiple oxidation states and forms, commonly seen as -2, 0, +4, +6, existing in nature as the elemental form, sulfides, or sulfates. The elemental forms include yellow crystalline sulfur and red liquid sulfur. There are many sulfides such as hydrogen sulfide, iron sulfide, copper sulfide, varying in color and properties. Many sulfates also exist, such as sulfuric acid, ammonium sulfate, calcium sulfate, which serve as raw materials or by-products for various industries and agriculture. 硫对所有生物都是必需的元素，它是多种氨基酸和蛋白质的组成部分，也是许多维生素和酶的成分。硫参与了生物体的许多重要的生理功能，如能量代谢、抗氧化、免疫调节、信号传导等。没有硫，生命就无法存在。 Sulfur is an essential element for all living organisms. It is a component of many amino acids and proteins, as well as vitamins and enzymes. Sulfur participates in many important physiological functions in biological systems, such as energy metabolism, antioxidation, immune regulation, and signal transduction. Life cannot exist without sulfur.
