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. .

You will need to repeat the steps to get N leaching index for the major component(s) of each map unit.. Then make a table or spreadsheet to record the results of the calculations for each map unit component.. Why are metals used to make these items?. Properties of metals . What property of metals is being . utalised. in the images on the previous slide?. Fishing sinker. Cooking pot. Electrical wires. Bread ties. 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.. METAL CHEMISTRY. N4.
