Answer 2

Elements in Order of Decreasing Metallic Properties:

1. Calcium 2. Copper 3. Germanium 4. Selenium 5. Potassium

The elements can be arranged in the order of decreasing metallic properties as follows: 1. Calcium - Calcium is a chemical element with the symbol Ca and atomic number 20. It is a fairly reactive metal and is essential for living organisms, particularly in cell physiology. 2. Copper - Copper is a chemical element with the symbol Cu and atomic number 29. It is a soft, malleable, and ductile metal with very high thermal and electrical conductivity. 3. Germanium - Germanium is a chemical element with the symbol Ge and atomic number 32. It is a lustrous, hard, grayish-white metalloid in the carbon group, chemically similar to its group neighbors tin and silicon. 4. Selenium - Selenium is a chemical element with the symbol Se and atomic number 34. It is a nonmetal with properties that are intermediate between the elements above and below in the periodic table, sulfur and tellurium. 5. Potassium - Potassium is a chemical element with the symbol K and atomic number 19. It is a soft, silvery-white alkali metal that oxidizes rapidly in air and is very reactive with water. This arrangement is based on the decreasing metallic properties of the elements listed.
