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 + .
The 2 electrons are on the first energy level. Period 2 Lithium Explain that lithium has 3 protons and 3 electrons. There are 2 electrons on the first energy level and 1 electron on the second. Explain that the first energy level can only have 2 electrons so the next electron in lithium is on the next (second) level. Neon
