They will learn about the main features of the Periodic Table and where the three egories of elements - metals, non-metals and semi-metals (also called the metalloids) - can be found. They will also learn that elements are arranged on the table according to their atomic nuers, starting with hydrogen (atomic nuer 1) at the top left hand corner and continuing from left to right across the
Uses of Alkali Metals - Science Struck
Alkali metals or Group 1A elements belong to a common group due to its ns 1 valence electronic configuration. The properties of an element have periodic dependence on its atomic nuer but not on atomic weight. These are similar to Group 17 (Halogens) in a way

Understanding Calcium Hardness - Taylor Technologies
Water with low calcium hardness will seek more by dissolving it from surfaces it comes in contact with that contain calcium, such as plaster, grout, and concrete decking. The late Dr. Neil Lowry, a well-respected instructor in our industry, preferred to call water with low calcium hardness "aggressive" rather than "corrosive" because the latter term implies the destruction of metals.

Calcium was named after the Latin term calx meaning lime, and is a reactive silvery metallic element found in Group 2 of the periodic table. It was first isolated in 1808 in England when Sir Humphry Davy electrolyzed a mixture of lime and mercuric oxide.
Activity of Metals
Metals in the fourth class are so unreactive they are essentially inert at room temperature. These metals are ideal for making jewelry or coins because they do not react with the vast majority of the substances with which they come into daily contact. As a result

As to the detergent action of a soap, Berzelius held that it was due to the free alkali liberated with water; but it is difficult to see why a solution which has just thrown off most of its fatty acids should be disposed to take up even a glyceride, and, moreover, on this theory, weak cold
How Does Chelation Work? - Life Enhancement Products
Chelation comes from the Greek word "claw," meaning "to grab," and that''s exactly what chelating agents do. Chelating agents like EDTA travel through the bloodstream "grabbing" on to minerals and metals, such as calcium, lead, mercury, cadmium, copper, aluminum and iron, binding them, removing them from the bloodstream, and delivering them to the kidneys, which excrete them in the urine.
KSEEB Class 10 Science Important Questions Chapter 3 …
Highly reactive metals such as sodium, calcium, aluminium, etc., are sometimes used as reducing agents because they can displace metals of lower reactivity from their compounds. For example, when manganese dioxide is heated with aluminium powder, manganese dioxide is reduced to metallic manganese while aluminium gets oxidized to aluminium trioxide.
