Brown algae (Phaeophyta) includes Kelps (Macrocystis, Laminaria) and Ascophyllum, Fucus, and Sargassum. Alginic Acid (Alginate) is a colloidal product used for thickening, suspending, stabilizing, emulsifying, gel-forming, or film-forming, as required. 1  About half of the alginate produced is used for making ice cream and other dairy products, the rest is used in other products, including shaving cream, rubber, or paint.
Lithium is a Group 1 (IA) element containing just a single valence electron (1s 2 2s 1). Group 1 elements are called alkali metals. Lithium is a solid only about half as dense as water and lithium metal is the least dense metal. A freshly cut chunk of lithium is silvery, but tarnishes in a minute or so in air to give a grey surface. Its chemistry is dominated by its tendency to lose an electron to form Li + .
Lithium (from Greek: Î»Î¯Î¸Î¿Ï lithos, stone) is a chemical element with symbol Li and atomic number 3.It is a soft, silver-white metal belonging to the alkali metal group of chemical elements.Under standard conditions it is the lightest metal and the least dense solid element.he transmutation of lithium atoms to helium in 1932 was the first fully man-made nuclear reaction, and lithium-6 deuteride serves as a fusion fuel in staged thermonuclear weapons.
