Answer 2

Elements in Increasing Order of Metallic Properties: Rb, Cs, Na, K

The elements Rb, Cs, Na, and K can be arranged in increasing order of metallic properties as follows:

1. Na (Sodium): Sodium is a highly reactive alkali metal with atomic number 11. It has a metallic character and is known for its high electrical and thermal conductivity. Sodium is less metallic than the other elements in the list.

2. K (Potassium): Potassium is another alkali metal with atomic number 19. It exhibits metallic properties such as high electrical and thermal conductivity. Potassium is more metallic than sodium.

3. Rb (Rubidium): Rubidium is an alkali metal with atomic number 37. It is more metallic than both sodium and potassium. Rubidium exhibits similar metallic properties to the other alkali metals.

4. Cs (Cesium): Cesium is the most metallic element among the four. It is an alkali metal with atomic number 55. Cesium has the highest electrical and thermal conductivity among the elements in the list.

The order of increasing metallic properties for the elements Rb, Cs, Na, and K is: Na < K < Rb < Cs.
