Lithium Lithium Lithium (from ) is a chemical element with symbol Li and atomic number 3. It is a soft, silvery-white alkali metal. Under standard conditions, it is the lightest metal and the lightest solid element. Like all alkali metals, lithium is highly reactive and flammable, and is stored in mineral oil. When cut, it exhibits a metallic luster, but moist air corrodes it quickly to a dull silvery gray, then black tarnish. It never occurs freely in nature, but only in (usually ionic) compounds, such as pegmatitic minerals which were once the main source of lithium. Due to its solubility
Solid (web decentralization project) in a specific pod. The user retains complete ownership and control of data in the user's pods: what data each pod contains, where each pod is stored, and which applications have permission to use the data. In more detail, Solid consists of the following components: Solid (web decentralization project) Solid (Social Linked Data) is a web decentralization project led by Tim Berners-Lee, the inventor of the World Wide Web. The project is run from the Massachusetts Institute of Technology (MIT). The project "aims to radically change the way Web applications work today, resulting in true data ownership as well as
