rfntbrfntrtbrtntt. This instability is what drives the process of corrosion and it results from the fact that a refined metal is continually trying to revert to its natural state the mineral Some metals do this faster than others The Galvanic Series ranks corrosion te T’Keyah Driskell. &. Lyric Williams. I. ntroduction. In our PowerPoint Presentation, we will be explaining what alkaline earth metals are and some of their uses, reactions, properties, etc. . We will tell what the four metals in the group are, and their mass, density, and melting point are. . Application. Property. Metal. Non-metal. Colour. Metals can be polished to a high gloss. Mercury is used in the manufacture of mirrors. Some paints which are used as interior paints are lustreless.. The abundance of the metals in the Earth's surface varies greatly.. Only metals that occur in concentrated deposits - called ores - are economically valuable.. About 23,000 kg of materials are extracted from the surface and processed per person in our country each year.. Anthony Cosimano. Elements on the lower periodic table found in the earth’s crust. A few of these elements are used heavily in the production of technologically advanced goods. Such as....

Elements in Group 1 are called . alkali metals. . lithium, sodium, potassium, rubidium, cesium, and francium . • Alkali metals are so named because they are metals that react with water to make alkaline solutions. . HL: Locate the alkali metals on the periodic table.. HL: Describe the properties of the alkali metals.. HL: Describe the reactions of the alkali metals with air.. HL: Describe the reactions of the alkali metals with water using word equations.. Patel Sikora. What are Alkali Metals?. The alkali metals are located in Group 1 of the periodic table. They are a series of chemical elements which have similar trends and properties. Alkali metals are so called because when they react with water alkalis (strong bases that can neutralize acids) are formed..
